Everything we feel, think, do, remember. Every joy, sadness, pain, ecstacy are all different notes in the neuronal symphony we call a brain.
Central nervous system is the spinal cord and the brain, and the other nerves are the peripheral nervous system sensory neurons motor neurons interneurons
Let’s take a look at a single neuron. It is a complex dynamic structure that is built to transmit a signal. An action potential. When stimulation to the cell body and/or dendrites is sufficient, the nerve cell will open ion channels along the length of the neuron and axon. And this will create a charge that will travel down the axon to the terminal from which a chemical messenger will be released. This is called a neurotransmitter. There are over 60 neurotransmitters – a couple that you are probably familiar with are dopamine, serotonin, neurepinephirine, and histamine.

Both conditions showed increased occipital functioning in both compared with baseline
Insula, orbitofrontal cortex, nucleuus accumbens and right cingulate gyrus
Brain circuits are affected by drug abuse and addiction . The areas depicted contain the circuits that underlie feelings of reward, learning and memory, motivation and drive, and inhibitory control. Each of these brain areas and the behaviors they control must be considered when developing strategies to treat drug addiction. PFC – prefrontal cortex; ACG – anterior cingulate gyrus; OFC – orbitofrontal cortex; SCC – subcallosal cortex; NAcc – nucleus accumbens; VP – ventral pallidum; Hipp – hippocampus; Amyg – amygdala

Addiction changes brain circuitry making it hard to “apply the brakes” to detrimental behaviors . In the non-addicted brain, control mechanisms constantly assess the value of stimuli and the appropriateness of the planned response, applying inhibitory control as needed. In the addicted brain, this control circuit becomes impaired through drug abuse, losing much of its inhibitory power over the circuits that drive response to stimuli deemed salient.
