Concept explainers
To determine:
The outline of two mechanisms by which information flow between two neurons in adults can increase.
Introduction:
Neuron is an excitable cell which receives the information, process it and transmit it through chemical and electrical signals. The connections present between neurons to transmit the information are known as synapsis. The neural network can be formed by connection of neurons which are prime component of CNS (central nervous system) including spinal cord and brain and of PNS (peripheral nervous system) comprise of somatic nervous system and autonomous nervous system.
There are mainly three types of specialized neurons sensory neuron, motor neuron and interneuron. Sensory neuron stimulates with only particular stimuli and the motor neuron receives signals from spinal cord and brain and conveys it to different parts of the body whereas interneuron connects neuron to neuron with brain or spinal cord.
