Brain Response of Behavior

Part I

Note: Parts II and III follow below, complete all three.

Neurons process information through signals or nerve impulses in the brain. These are referred to as action potentials and the action is carried through two types of process. These processes are electrical and chemical synapse. Nerve impulse is the electrical signal reach from the chemical signal. the neuron receives it from another neuron through its dendrites. That chemical reaction between neurons is called a terminal buttons. The result, neurotransmitters are released which in turn transmit the message to the next neuron. The reactions between the neurons and signal transmitting are termed as synapses. The synapses do not gather together they exist as the synaptic cleft. Synaptic cleft is where and how the signals transfer through reaching the dendrite of a neuron. Once the neuron that receives information is known as a postsynaptic neuron and the one that sends the neuron is the presynaptic neuron. Then it returns to neurotransmitters that are released in the axon by the sacs named synaptic vesicles. A synaptic vesicles are often known as neurotransmitter vesicles. Stores a variety of neurotransmitters that function as chemical messengers to the next neurons. Neurotransmitters are released when they have a nerve impulse at the end of a axon and once they come across the synaptic cleft they will attack to the receptors of the receiving neuron called postsynaptic neuron. Terminal buttons must contain neurotransmitters of a certain shape to fit the receptor site and then the message is properly transmitted. Each neuron transmits only one kind of neurotransmitter and the way they receive and send the nerve impulses are known as excitatory and inhibitory. Excitatory sends a nerve signal and inhibitory are the ones that
