Brain Function

A Neuron is a specialized nerve cell that receives, processes, and transmits information to other cells in the body. Basically, it is the messenger cell responsible for receiving and transmitting information. Neurons are the information processing components of the brain, each part of the neuron is responsible for receiving and transmitting information. Each neuron please do use role in the communication of the flow of information throughout the body. Neurotransmitters neurotransmitter Chemical substance through which one neuron sends a message…

The Action Potential Is an Impulse of Electrical Activity

The action potential is an impulse of electrical activity. Action potential occurs when a neuron sends messages electrochemically down an axon called a nerve impulse. When a neuron is not stimulated or inactive, it is at resting potential. When a neuron is at rest, the electrical charge on the inside of the neuron is negative while the electrical charge on the outside of the neuron is positive. The resting membrane potential of a neuron is about -70 mV (mV =…

The Communication Process of Neurons in the Brain

Neurons in the brain communicate through each other through the process called synaptic transmission. In this process, the neurons in the brain are classified into two: the pre-synaptic neuron and the post-synaptic neuron. The pre-synaptic neuron is the neuron which carries the electrical impulse that will be sent to the adjacent neuron. It is called pre-synaptic because it is the neuron before the synapse. The adjacent neuron is the receiving neuron and it is called post-synaptic neuron since it is…

Worksheet – Membrane Potentials

Introduction to Membrane Potentials 1.Describe the neuron function. Neurons act to facilitate the transfer of data amongst the body’s cells sustaining homeostasis 2.Contrast graded potentials and action potentials. Graded potentials are electrical signals that have variable amplitude, are localized, and travel short distances along the membrane. In contrast, an action potential has a fixed amplitude, and can travel greater distances along the membrane. 3.a. Describe how there can be an electrical change on either side of a membrane thereby generating…
