A new study reveals how the brain compensates for rapid eye movements, maintaining a stable visual perception despite dynamic visual input. Researchers found that this stability mechanism breaks down for non-rigid motion like rotating vortices.
A study found that exposing older adults to various odorants at night using an odorant diffuser improved their memory and increased activity in the uncinate fasciculus.
A comprehensive guide to brain maps compiled by a space shuttle guidance system engineer, detailing the brain's advanced circuitry and its comparisons to sophisticated technology.
The article discusses various regions of the brain, highlighting their functional roles in vision, balance, navigation, and computational processing.
1. **Lateral Occipital Complex (LOC)**:
- Role in object recognition.
- High accuracy and speed in recognizing visually presented objects.
2. **Cerebral Cortex**:
- A 6-layer circuit board with processing power surpassing 34,500 Intel i7 quad-core processors.
- Processes live vision to extract shapes and edges.
- Forwards information to regions detecting faces, facial expressions, objects, and body parts.
- Sends data to emotional and reward centers in the orbital and prefrontal cortex.
3. **Vestibule**:
- Similar to a 3-axis gyro and accelerometer used in military guidance and navigation systems.
- Measures linear and rotational acceleration in three dimensions.
- Provides navigational data, controls balance, stabilizes vision, and helps keep eyes on a target.
- Connected to the cerebellum and other regions for inertial navigation and movement tracking.
4. **Retina**:
- Contains over 125 million rod photoreceptors processing motion and visual reflexes.
- More computational power than five iPhone 6 processors.
- Controls muscles directly to avoid objects and preserve life.
- Computes specific visual scene information using various ganglion cell types.
5. **Thalamus (Medial Dorsal Nucleus, Parvocellular Nucleus)**:
- Over 6.3 million different connections.
- Plays a role in visual processing and relaying sensory information to the cerebral cortex.
6. **Inferior Parietal Sulcus (IPS)**:
- Involved in complex hand use, reaching, grasping, and programming intentional hand movements.
- Matches visual and body-centered frames of reference.
7. **Brainstem and Cerebellum**:
- Controls visual reflexes using the vestibulocerebellum.
- Inertial navigation system calculating movement through space.
8. **Visual Cortex**:
- Sequential computations from low-level to high-level properties of visual stimuli.
- Processes shapes, edges, and global object shapes.
9. **Prefrontal Cortex**:
- Involved in decision-making, emotional regulation, and reward processing.
10. **Occipital Lobe**:
- Key in visual processing and recognizing objects.

The default mode network (DMN) plays a critical role in human creativity and the generation of ideas, according to recent studies. Researchers are exploring how manipulating this network can influence creativity.
A new study reveals that when engaging in complex cognitive tasks, the brain's activity becomes more detailed and streamlined, allowing for efficient processing. The findings suggest the brain adjusts its patterns of activity to match task demands.
A study reveals that the brain stores memories in three parallel copies using different sets of neurons. This could have implications for treating traumatic memories.
Researchers have gained new insights into how the hippocampus generates and sustains oscillations, which will be helpful for informing models on how the brain region works.
A new study reveals the role of the molecule KIBRA in forming long-term memories. Researchers found that KIBRA acts as a “glue,” binding with the enzyme PKMzeta to strengthen and stabilize synapses, crucial for memory retention.
Recent volumetric brain reconstructions reveal high anatomic complexity. Research shows brain anatomy satisfies universal scaling laws, implying criticality in the cellular brain structure. Findings enable comparisons of structural properties across different organisms.
Researchers discovered that the brain interprets negated adjectives differently than affirmative ones, exhibiting a mitigating rather than inverting effect. This finding contributes to the understanding of how the brain processes negation and other complex linguistic operations.
