It provides a state of heightened neural activity due to more excitatory neurotransmitters present within synaptic clefts of neurons. This extra molecular presence within the synaptic gaps can lead to stabilizing and more homeostatic dopamine-like concentrations within

Drugs take the place of our natural body functions of the body. They fool receptors of the body and make it to where

Nerve cells use a brain chemical called dopamine to help control muscle movement. Parkinson ’s disease occurs when the nerve cells in the brain that make dopamine are slowly destroyed. Without dopamine‚ the nerve cells in that part of the brain cannot properly send messages. This leads to the loss of

A person with Parkinson’s experiences different kinds of symptoms like: Tremors‚ bradykinesia‚ pore posture‚ loss of balance‚ stiffness and hallucinations or delusions.

Within the brain‚ the main structures that determine mood and behavior are the amygdala‚ the thalamus‚ and the hippocampus. The amygdala is associated with emotions such as anger‚ pleasure‚ sorrow‚ fear‚ and sexual arousal. The thalamus is the region of the brain responsible for speech‚ behavior and movement. The hippocampus helps internalize certain events and creates long-term memory. Recent evidence identifies certain alterations in these areas of the brain in people suffering from depression
