That means that it is not going under depolarization‚ we use the term resting potential. Modality gated channels- specific to sensory neurons‚ open in response to mechanical forces (i.e. stretch‚ touch‚ pressure‚ temperature changes or chemicals) Ligand- is a particular molecule that causes

Synaptic Cleft Structure and Function Elizabeth Moreno Biochemistry at TMI Abstract A synaptic cleft is the space between neurons at a nerve synapse across which a nerve impulse is transmitted by a neurotransmitter—called also synaptic gap (Merriam-Webster) . This paper will utilize this simple definition in order to understand the synaptic cleft. Furthermore‚ we will explore the complex functions and the structure of the synaptic cleft. This will then allow for an in depth analysis

Myelin Sheath In a neuron‚ the myelin sheath consists of fat-containing cells that insulate the axon from electrical activity. This can be compared such as the insulation of a house. The main purpose of the insulation is to increase the rate of transmission of signals in the neuron. There is a small gap between each myelin sheath cell along the axon. Since fat inhibits the proper agitation of electricity‚ the signals jump from one gap to another. The destruction or loss of the myelin sheath in

Humans have in the range of 100 billion neurons (nerve cells) in their own nervous system‚ in comparison to organisms such as simple worms which may have as little as a few hundred cells (Franks‚ 2012). It is this complex network of neurons which‚ working in harmony with the many other structures and organs that make up our bodies‚ can transform otherwise meaningless vibrations into the haunting

will be discussed are the enrichment of certain environments on brain plasticity and the observation of experiences actions on the activation of mirror neurons. The first effect of environment on physiological processes that will be discussed is brain plasticity. Brain plasticity is the brain’s ability to rearrange its connections with its neurons‚ that is‚ the changes that occur in the structure of the brain as a result of learning or experience (exposure to different environments). The changes
