A Synapse is the " junction between the processes of two neurons or between a neuron and an effector organ, where neural impulses are transmitted by chemical means. The impulse causes the release of a neurotransmitter (e.g., acetylcholine or norepinephrine) from the presynaptic membrane of the axon terminal. The neurotransmitter molecules diffuse across the synaptic cleft, … Continue reading Synapse
A Neural Pathway is a series of neurons connected to form a route along which electrochemical impulses travel to convey information from one brain region to another.
A neuron is "A nerve cell that receives and sends electrical signals over long distances within the body. A neuron receives electrical input signals from sensory cells (called sensory neurons) and from other neurons. The neuron sends electrical output signals to muscle neurons (called motoneurons or motor neurons) and to other neurons. A neuron that … Continue reading Neuron
Neurogenesis "is the process by which new neurons are formed in the brain. Neurogenesis is crucial when an embryo is developing, but also continues in certain brain regions after birth and throughout our lifespan."
A Neurotransmitter is a chemical messenger released by neurons to stimulate neighboring neurons, muscles, or gland cells. There are many neurotransmitters, including Dopamine, Acetylcholine, and Glutamate. Here's a look at types of neurotransmitters: https://youtu.be/FXYX_ksRwIk Here's a quick look at how neurotransmission works: https://youtu.be/p5zFgT4aofA
Dopamine is a neurotransmitter that plays many important rolls in both the brain and body. Dopamine "is a neurotransmitter, one of those chemicals that is responsible for transmitting signals in between the nerve cells (neurons) of the brain. Very few neurons actually make dopamine. " Because it is such an important part of the brain's … Continue reading Dopamine
Glutamate is "a neurotransmitter that excites cells of the central nervous system." "Glutamate is considered to be the major mediator of excitatory signals in the mammalian central nervous system and is involved in most aspects of normal brain function including cognition, memory and learning."
The Cerebral Cortex is the "furrowed outer layer of gray matter in the cerebrum of the brain, associated with the higher brain functions, as voluntary movement, coordination of sensory information, learning and memory, and the expression of individuality." The cerebral cortex is involved in many body functions, including: Determining IntelligenceDetermining PersonalityMotor FunctionPlanning and OrganizationTouch SensationProcessing Sensory … Continue reading Cerebral Cortex
A Dendrite is a short branched nerve cell extension along which received impulses from other cells travel to the cell body. To reach a dendrite, impulses travel across a synapse from the axon of another cell.
According to medicinenet.com, Cortisol is "A metabolite of the primary stress hormone cortisone. Cortisol is an essential factor in the proper metabolism of starches, and it is the major natural glucocorticoid (GC) in humans." According to a Psychology Today article, Cortisol is "public health enemy number one. Scientists have known for years that elevated cortisol levels: interfere with learning and memory, … Continue reading Cortisol
An Axon is a long, threadlike, appendage of a nerve cell that carries impulses away from the cell body to other cells. Axons connect via a synapse to dendrites.
Neuroplasticity refers to the brain's "ability to reorganize itself by forming new neural connections throughout life. Neuroplasticity allows the neurons (nerve cells) in the brain to compensate for injury and disease and to adjust their activities in response to new situations or to changes in their environment. Brain reorganization takes place by mechanisms such as … Continue reading Neuroplasticity
