tetrodotoxin TTX
Potent neurotoxin that selectively blocks voltage-gated sodium channels, preventing action potential generation.
center-surround receptive field
Circular receptive field organization with opposite responses in center and surrounding regions.
connectome
Comprehensive map of neural connections within a nervous system or brain region.
cytoarchitecture
Organization and arrangement of cell types within neural tissue, particularly cortical layers.
ectopic spike
An action potential that originates from an abnormal location along the axon rather than the normal initiation site.
electrocorticography
Recording of electrical activity directly from the brain surface using electrodes placed on the cortex.
electroencephalography
Non-invasive technique for recording electrical activity of the brain through electrodes placed on the scalp.
ionotropic receptor
Ligand-gated ion channel that opens directly upon neurotransmitter binding.
metabotropic receptor
G-protein coupled receptor that activates intracellular signaling cascades upon neurotransmitter binding.
population vector
Mathematical representation of movement direction decoded from multiple motor cortex neurons.
receptive field
The specific region of sensory space where stimuli can influence a neuron's firing rate.
stereotactic electroencephalography
An invasive technique using depth electrodes placed with stereotactic precision to record intracranial EEG for epilepsy...
