To determine:
How does a neuron generate and transmit impulse.
Concept introduction:
Neuron is also called nerve cells is the fundamental unit of brain. It transmits information in the form of electrical and chemical signals in response to external stimuli. It is made of cell body, dendrite and axon.

- What mechanisms stabilize neural circuits?arrow_forwardThe purpose of an action potential (AP) is to propagate a signal down the axon to the axon terminal. What happens once it reaches the axon terminal? Using the experiment showing recordings from the post-synaptic cell (endplate potentials), describe what happens when an AP reaches the axon terminal and subsequently transmits the signal to a neighboring cell. What does this tell us about chemical neurotransmission?arrow_forwardWhat is an axon terminal?arrow_forward
