Study Notes

Connectome

A complete map of all neural connections in the brain.
Shows how neurons and brain regions are connected.
Understanding consciousness, memory, and mental processes will benefit from it.

Brain Atlas

A map of brain cells and structures used in neuroscience.
Guides understanding of different brain cell types and their roles.
A complete cellular atlas helps understand the human brain compared to others.

BRAIN Initiative

A research program by the NIH focused on brain study technologies.
Funds research on brain imaging, mapping, and brain-computer interfaces.

Human Brain Project

A European Union project using neuroscience and AI to study the brain.
Aims to create simulated brain models for studying brain disorders.

Brain/MINDS Project

A Japanese neuroscience initiative studying marmoset brains.
Marmosets have similar brain structures to humans, making them a model for studying human higher brain function and neurodevelopmental disorders.

Neurogenesis

The process of creating new neurons.
Once thought to cease in adulthood, ongoing research investigates its continuation.
Potential new treatments for neurodegenerative disorders, like Alzheimer's, if neurogenesis exists.

Brain Organoids

Miniature brain models made from stem cells.
Studying brain development and neurodegenerative diseases in the lab.
Future potential for repairing damaged brain tissue.

Optogenetics

Uses light to control neuron activity.
Neuroscientists activate or deactivate specific neurons to understand their function.

Chemogenetics

Uses chemicals instead of light to manipulate neurons.
Provides longer, more stable control of neural circuits; useful for studying behavior and brain disorders.

Transcranial Magnetic Stimulation (TMS)

A non-invasive method using magnetic fields to stimulate brain activity.
Treats depression and other neurological conditions; research on cognitive function.

Neural Interfaces (Brain-Computer Interfaces, BCIs)

Technology for direct brain-computer/prosthetic communication.
Helps those with paralysis control artificial limbs and communicate.

Single-Cell Transcriptomics/Proteomics

Examines gene expression and protein composition in individual brain cells.
Understanding brain cell diversity and how cells change in conditions like neurodegenerative diseases.

Artificial Intelligence (AI) in Neuroscience

Uses AI and machine learning to analyze and understand the brain.
Speeding up brain scan analysis, disease biomarker identification, and improved brain models.

Epigenetics in the Brain

Study of how environmental and lifestyle factors affect gene expression without changing DNA.
Explains how stress, nutrition, and other factors affect brain health and mental disorders.

Positron Emission Tomography (PET) Imaging

A brain imaging technique using radioactive tracers to observe brain activity.
Used in research and diagnosis of Alzheimer's disease and other neurological disorders.
