Parts of the Brain
The region of the cerebral cortex responsible for vision.
What is the occipital lobe?
This disease is typically characterized by plaques of amyloid-beta and tau neurofibrillary tangles.
What is Alzheimer's Disease?
The fatty insulating layer that covers neuronal axons, contributing to faster signaling.
What is the Myelin Sheath?
The neurotransmitter primarily responsible for motor function.
What is Acetylcholine?
The average brain weighs this many pounds.
What is 3?
The almond shape structure responsible for the perception of fear and anger.
What is a stroke?
Star-shaped glial cells that regulate extracellular ions/neurotransmitters and help maintain the blood–brain barrier.
What are astrocytes?
This neurotransmitter is deeply associated with pleasure and reward!
A rapid, short-lasting decrease in synaptic strength due to vesicle depletion at a presynaptic terminal.
What is LTD?
This circuit helps to fine tune motor movements, known for its indirect and direct pathways.
What is the basal ganglia?
This disorder involves a dysregulation of dopamine transmission, with positive and negative symptoms noted.
What is Schizophrenia?
The PNS glial cell that myelinates axons and plays a big role in peripheral nerve regeneration.
What are Schawnn cells?
SSRIs (common antidepressants) target the reuptake of this neurotransmitter.
What is serotonin?
Who is Henry Molaison (HM)?
The nucleus of the thalamus that recieves visual input from the optic nerves.
Lateral Geniculate Nucleus (LGN)
Inflammation of the membranes that line the skull.
What is Meningitis?
This glial cell type is responsible for creating cerebrospinal fluid (CSF).
What are ependymal cells?
This class of neurotransmitters are synthesized from tyrosine. Examples: Dopamine, Norepinephrine
What are catecholamines?
In optogenetics, this light-gated ion channel is used to depolarize neurons—often with blue light
This tiny hypothalamic nucleus acts as the body’s master clock, syncing circadian rhythms to light.
What is the suprachiasmatic nucleus (SCN)?
The leading inherited genetic cause of autism, a genetic disorder.
What is Fragile X Syndrome?
The common excitatory, glutamatergic projection neuron of the cerebral cortex—named for its triangular soma and long apical dendrite.
What are pyramidal neurons?
This ‘backward’ messenger is synthesized postsynaptically and diffuses to presynaptic CB1 receptors to reduce neurotransmitter release.
What are endocannibinoids?
During early neural development, this funny-named signaling molecule secreted from the notochord and floor plate ventralizes the neural tube—specifying fates in a concentration-dependent gradient.
What is sonic hedgehog?
