Ionotropic receptors

Ligand-gated ion channel (a receptor protein containing an ion channel that opens when the receptor is bound by an agonist)

Metabotropic receptor

A receptor protein that doesn’t contain ion channels but may, when activated, use a second messenger system to open nearby ion channels or to produce other cellular effects.

Meninges

Cerebral spinal fluid

Neuroscience terms

People are more likely to believe neuroscience if it contains…

Oligodendrocytes, Schwann cells, astrocytes, microglial cells

The 4 types of glia

Microglial cells

Small glial cells that remove cellular debris from injured or dead cells

Astrocytes

Control local blood flow, form tough outer membranes that swaddle the brain, secrete chemical signals

Oligodendrocytes (CNS)

Wraps itself and forms myelin in the central nervous system

Schwann Cells

Glial cells that wraps itself and forms myelin in the PNS (peripheral nervous system)

EPSP

Depolarizing potential that is caused by synaptic excitation. These increase to probability of a postsynaptic neuron firing an action potential

IPSP

A hyperpolarizing potential in a neuron. These decrease the probability that a postsynaptic neuron will fire an action potential

Afferent

Carries AP (or info) to the brain/region of interest

Efferent

Carrying AP (or info) away from the brain or area of interest

PET scan

Brain imaging technology tracking metabolism or injected radioactive substances in the brain for brain activity
