Build a premium 3D Interactive Human Brain Explorer using the existing hero template as the structural foundation.

The website should feel like a futuristic neuroscience lab where users can explore the human brain, understand what different regions do, and interact with a detailed 3D brain model.

Keep the existing React + Next.js + shadcn + Tailwind + TypeScript structure, but completely redesign the visual experience around neuroscience and interactive 3D exploration.

Core concept

Create a website called NEURO//MAP.

Headline:

Explore the Most Complex Object We Know

Subheadline:

An interactive 3D map of the human brain and the systems behind memory, emotion, movement, language, and thought.

Primary CTA:

Explore the Brain

Secondary CTA:

View Brain Regions

3D Hero Experience

Replace the existing DNA video with a fully interactive 3D human brain built with:

three
@react-three/fiber
@react-three/drei

The hero should feature a large anatomically inspired 3D human brain positioned slightly toward the right side of the screen.

The brain should have a realistic overall shape while maintaining a clean, futuristic scientific aesthetic.

Visually divide the brain into major regions using subtle differences in material, transparency, lighting, and glow.

Include areas such as:

frontal lobe
parietal lobe
temporal lobe
occipital lobe
cerebellum
brainstem
hippocampus
amygdala
thalamus
hypothalamus
motor cortex
visual cortex
prefrontal cortex

The brain should slowly rotate when idle.

Mouse movement should subtly influence its orientation.

Users should be able to drag to rotate the brain.

Scrolling or pinch gestures should allow controlled zooming.

Hovering a brain region should:

softly highlight the region
slightly separate it from surrounding anatomy
display the region name
show a short description
draw a thin glowing connector line to an information label

Clicking a region should smoothly focus the camera on it and open a detailed information panel.

Neural Activity

Add subtle neural activity inside the brain.

Create animated particles or pulses that travel along branching neural pathways.

The effect should resemble electrical signals passing through neurons.

Keep this subtle and scientifically inspired rather than turning the brain into a glowing sci-fi object.

Occasional pulses should move between different brain regions.

When a user hovers over a region, neural activity around that region should increase slightly.

Hero Layout

Keep the general layout style of the supplied component.

Left side:

NEURO//MAP logo

Headline:

Explore the Most Complex Object We Know

Description:

Interact with the human brain and learn how different regions influence memory, emotion, movement, vision, language, decision-making, and behavior.

Buttons:

Explore the Brain →

View Brain Regions

Right/background:

The interactive 3D brain.

The brain should feel like it is floating inside a dark research environment.

Visual Direction

The interface should feel like a combination of:

neuroscience research software
medical visualization
futuristic laboratory UI
scientific museum exhibit
premium spatial computing interface

Use a near-black background with soft off-white typography.

Use subtle accents of:

electric blue
violet
cyan
warm neural-orange for electrical activity

Do not make every element glow.

Use light strategically.

Add very subtle:

scientific grid lines
anatomical labels
coordinate markers
floating measurements
scan-line details
depth indicators

The result should feel sophisticated, educational, and cinematic.

Navigation

Replace the existing navigation with:

Brain
Regions
Systems
Neurons
Memory
About
Right side:
Search
Explore
The navigation should remain transparent when the page loads.
After scrolling, transform it into a floating glass navigation bar with:

dark translucent background

backdrop blur

subtle border

rounded corners

Keep the existing scroll behavior.

Brain Region Slider
Replace the existing company logo slider.
Use the heading:
Explore major brain regions

Create the infinite slider using region names:

Frontal Lobe
Parietal Lobe
Temporal Lobe
Occipital Lobe
Cerebellum
Hippocampus
Amygdala
Thalamus
Brainstem
Prefrontal Cortex

Use small minimalist icons or anatomical symbols where appropriate.

Preserve the existing progressive blur effect on both sides.

Interactive Brain Explorer Section

Create a large dedicated section titled:

Inside the Human Brain
Place a larger interactive 3D brain in the center.
Add a side panel with filters.
Users should be able to filter by brain function:
Memory
Emotion
Movement
Language
Vision
Hearing

Decision Making

Sleep

Hormones

Attention

When a category is selected, highlight the relevant regions.

Example:

Selecting Memory should highlight:

hippocampus

prefrontal cortex
amygdala
Selecting Movement should highlight:
motor cortex
cerebellum
basal ganglia
Selecting Vision should highlight:
occipital lobe
visual cortex
Dim unrelated regions without completely hiding them.

Brain Region Detail Panels

When users click a region, open an elegant floating panel.

Example:

Hippocampus
Category:
Memory & Learning

Description:

The hippocampus plays an important role in forming new memories, spatial navigation, and learning.
Show:
location

primary functions

connected regions
interesting facts

associated cognitive processes

Include a Locate in Brain button that repositions the 3D camera.

Brain Systems Section

Create an interactive section titled:

How the Brain Works Together

Instead of treating each region independently, visualize functional networks.

Include:

Default Mode Network
Salience Network
Executive Control Network
Visual Network
Motor Network
Language Network
Limbic System

Display these networks as animated pathways connecting multiple brain regions.

Hovering a network should highlight all regions participating in that network.

Neuron Explorer
Create a separate 3D section titled:
Inside a Neuron
Display a large interactive neuron.
Include:

dendrites

cell body

nucleus

axon

myelin sheath

axon terminals

synapses
Animate an electrical signal traveling from the dendrites through the axon.
Users should be able to click each structure to learn what it does.
Add a button:
Fire Neuron
When clicked, animate an action potential traveling across the neuron.
Synapse Interaction

Create a close-up visualization of two neurons communicating.

Show neurotransmitter particles traveling across the synaptic gap.

Allow users to trigger the transmission manually.

The animation should explain:

electrical signal reaches the axon terminal

neurotransmitters are released

molecules cross the synaptic cleft

receptors receive the signal
the next neuron responds
Keep the explanation visual and interactive.
Brain Function Cards
Create large interactive cards for:
Memory
Emotion
Movement
Language
Vision
Sleep
Attention
Decision Making
Each card should contain:

a small 3D or animated visual

short description

relevant brain regions

Hovering cards should use subtle depth and tilt effects.

Brain Hemisphere Interaction

Add a section comparing the left and right hemispheres.

Display the brain split down the middle.

Users should be able to drag the two hemispheres apart slightly.

Show major functional differences while avoiding oversimplified claims such as "left brain = logical, right brain = creative."

Explain that most complex tasks involve networks across both hemispheres.

Brain Scan Mode
Add a toggle:
Anatomy / Neural Activity / Functional Networks
Anatomy mode:
Show clear brain regions.
Neural Activity mode:
Show animated signals and activity hotspots.

Functional Networks mode:
Show connections between regions.

Transitions between modes should be smooth.

Scroll Experience

Use scroll-based storytelling.
As the user scrolls:
start with the full brain
rotate toward a side view
separate major lobes
zoom into the hippocampus
travel deeper into neural tissue
transition into a neuron

zoom toward a synapse

Make these transitions feel continuous where possible.
Use camera movement instead of abrupt section changes.
Motion

Use motion/react for interface animations.

Use React Three Fiber for 3D scenes.

Include:

smooth camera transitions

scroll-triggered rotations

cursor-follow movement

neural pulses

hover highlighting

region separation

depth transitions

floating annotations
subtle parallax

Animations should feel controlled and scientific rather than playful.
Search Feature

Add a brain search feature.
Users should be able to search terms such as:

"memory"

"fear"

"vision"

"speech"

"sleep"
"movement"
"Hippocampus"
"Broca's area"
The site should return relevant brain regions and automatically focus the 3D brain on them.
Mobile Experience
The website must remain highly interactive on mobile.

Support:

drag rotation

pinch zoom

tap-to-select brain regions

Reduce:

particle count

neural pathway density
advanced blur effects
unnecessary post-processing
Keep the brain model as the main visual experience.
Accessibility
Provide accessible alternatives for 3D interactions.
Every brain region should also be available through regular HTML controls.
Users should be able to navigate brain regions using the keyboard.
Respect prefers-reduced-motion.

Disable large camera movements for users who prefer reduced motion.

Performance

Optimize the 3D scenes carefully.

Use:

compressed GLTF/GLB models

Draco compression where appropriate

lazy-loaded lower-page scenes

Suspense

adaptive DPR

mesh simplification on mobile

reusable materials

efficient lighting

minimal post-processing

Do not render multiple expensive 3D scenes simultaneously when they are offscreen.

Required libraries

Install if missing:

npm install three @react-three/fiber @react-three/drei motion lucide-react @radix-ui/react-slot class-variance-authority framer-motion react-use-measure
Component Structure
Create reusable components such as:

/components/three/BrainModel.tsx
/components/three/BrainRegion.tsx
/components/three/NeuralActivity.tsx
/components/three/NeuronModel.tsx
/components/three/SynapseScene.tsx
/components/three/BrainNetworks.tsx

/components/sections/BrainExplorer.tsx
/components/sections/BrainSystems.tsx
/components/sections/NeuronExplorer.tsx
/components/sections/BrainFunctions.tsx

/components/ui/brain-info-panel.tsx
/components/ui/brain-search.tsx
/components/ui/function-filter.tsx
/components/ui/mode-toggle.tsx

Important implementation requirements
Use the supplied component as the starting structure rather than building an unrelated website.
Preserve:
responsive navbar

mobile menu

infinite slider

progressive blur

shadcn buttons

scroll-aware navigation

general hero composition

Replace:

branding

logo

hero text

navigation
company logos
DNA video
SaaS content
Do not fake the brain using a simple sphere.
Use or create an anatomically recognizable 3D brain model.
If an external brain GLB/GLTF asset is required, structure the component so the model can easily be placed inside /public/models/brain.glb.
Do not create placeholder boxes where 3D content should exist.
Actually implement the Three.js interactions.

Prioritize the 3D brain experience first before building secondary sections.

The final result should feel like a digital neuroscience exhibit someone would naturally rotate, click, zoom into, and spend time exploring.
