Neural Representations and Neuronal Signaling

Flashcards covering key concepts related to neuronal signaling, action potentials, synaptic transmission, and neural representation.

Action Potentials

A rapid change in the voltage of a cell's membrane indicating that the neuron has fired.

Synaptic Transmission

The chemical transmission of signals from the pre-synaptic neuron to the post-synaptic neuron, facilitating neuronal communication.

Receptive Field

A limited region of space within the visual field where a neuron responds to stimuli.

Single Cell Recording

A technique that involves recording action potentials from an individual neuron.

fMRI

Functional Magnetic Resonance Imaging; a method that detects changes related to metabolic activity in the brain.

Neuronal Circuit

A network of interconnected neurons that communicate with each other, facilitating the processing of information.

Metabolically Active Cells

Cells that absorb radioactive agents, indicating their response to stimuli in the context of functional imaging.

Tonotopic Map

A spatial representation of sound frequencies in the primary auditory cortex.

Olfactory Bulb

The brain structure responsible for processing scent information, showing distinct activation patterns for different scents.

Neuronal Population

A group of neurons that collectively respond to stimuli, often measured using functional imaging techniques.
