3 and 2.4. Write a 350- to 700-word response to the following: Explain the communication process of neurons in the brain. List some common neurotransmitters and describe their effect on behavior. <Insert Response Here> The communication process of neurons in the brain occurs through an electrochemical process. Neurons pass neurotransmitters through the dendrites‚ which are attached to the ends of each neuron and receive messages from neighboring neurons. The chemical messages that

Dendrite: branching neuron structures that receive neural impulses from other neurons and convey impulses toward the cell body 2. Axon: long tube like structure that conveys impulses

Where are they stored in the neuron within motor neuron endings 10. Neurotransmitters can be excitatory or inhibitory. Explain. Excitatory neurotransmitters decrease the negativity of postsynaptic membrane potentials; inhibitory

processes affect behaviour and impact the field of biological psychology Psychology as a field of study has evolved from the human need to understand ourselves and the causes behind our behaviours. Philosophy tried its hand first‚ attempting to describe it as a complex interaction between the mind and the body – between the mental and the physical. This basic idea resonates through this field of exploration through the years. While there have been diversions from this line of thought‚ tending towards

The electrical activity in a presynaptic neuron occurring at the chemical synapses causes the release of a chemical messenger called a neurotransmitter‚ which binds to neurotransmitter receptors on a postsynaptic neuron. Neurotransmitters are the chemical messengers that

becomes positively charged) and inhibitory (when the voltage inside the cell becomes negatively charged)‚ synaptic transmissions and receptors play a role in producing and regulating one’s behavior (Sahley‚ 2002). The process that follows describes how behavior is affected by the brain. A series of events takes place within the neuron of the axon hillock‚ between the axon and cell body.

instigates the release of neurotransmitters‚ which travel over the synapse‚ which is the gap between two neurons. Once the neurotransmitters cross the synapse‚ they go into receptor sites on the post-synaptic membrane of a neuron‚ and after having passed on the message‚ they are either broken down or reabsorbed by the terminal buttons of the neuron‚ in a process known as reuptake. Neurotransmission has been shown to affect a large range of human behaviors. Serotonin is a neurotransmitter that effects sleep

works by preventing the release of a neurotransmitter‚ acetylcholine‚ from the neurotransmitter junction‚ which does not allow the signal to travel pass through to be converted back into an electrical signal (Alberts‚ 2010).
