Front

What are metabotropic post-synaptic effects?

Back

Metabotropic post-synaptic effects are slow and long-lasting effects mediated by special receptors like G-protein coupled receptors.

Front

What happens to the body during REM sleep?

Back

During REM sleep, the body experiences atonia, leading to paralysis of postural muscles while the eyes move rapidly and genitalia become active.

Front

What is the auditory pathway responsible for?

Back

The auditory pathway is responsible for processing sound information from the environment.

Front

What is an action potential?

Back

An action potential is a wave of electrical activity that travels down the neuron's axon, initiated by the opening of sodium gates.

Front

What is exocytosis?

Back

Exocytosis is the process where vesicles filled with neurotransmitters dock on the cell membrane to release their contents.

Front

What is the resting voltage of a neuron at rest?

Back

The resting voltage of a neuron is approximately -70mV.

Front

What occurs when sodium gates open in a neuron?

Back

When sodium gates open, sodium ions enter the cell, making the inside of the cell more positive and changing the voltage to +40mV.

Front

What is the role of G-protein coupled receptors?

Back

G-protein coupled receptors are involved in metabotropic signaling, leading to slow and prolonged effects in the post-synaptic cell.

Front

What is atonia in the context of sleep?

Back

Atonia is the temporary paralysis of most voluntary muscles during REM sleep.

Front

What is synaptogenesis?

Back

Synaptogenesis is the process of forming new synapses between neurons.
