Neurons and Neurotransmitters
The chemical messenger released from a neuron to communicate with other neurons or muscle cells.
What is a neurotransmitter?
This lobe is located in the back of the brain, and mainly responsible for processing visual information.
What is the occipital lobe?
This neurodegenerative disorder is recognized by the progressive loss of memory and other cognitive functions.
What is Alzheimer's Disease?
This system connects the brain and spinal cord to the rest of the body and includes nerves like those in the arms and legs.
What is the peripheral nervous system?
The process by which our sensory organs take in stimuli from the environment, such as light or sound.
What is sensation?
The gap between two neurons
What area is the synapse located?
This lobe of the brain is mainly responsible for processing sensory information that the body sends.
What is the parietal lobe?
A disorder characterized by extreme mood swings, including manic and depressive episodes.
What is bipolar disorder?
This part of the brain is involved in regulating basic bodily functions such as breathing and heart rate.
What is the brainstem?
This is the brain's interpretation of the things it received through sensation, allowing us to make sense and interpret the world around us.
What is perception?
This part of the neuron carries electrical impulses away from the cell body.
What is an axon?
This lobe is located behind the forehead, and its main functions are decision making, problem solving and controlling behavior.
What is the prefrontal cortex?
This is a chronic neurological disorder that affects the brain's ability to regulate sleep-wake cycles, characterized by sudden sleep attacks
What is narcolepsy?
This part of the nervous system controls involuntary actions, such as the heartbeat, digestion, and breathing. "auto" = things we don't have to think about doing.
What is the autonomic nervous system?
The sense responsible for detecting changes in pressure, temperature, and pain.
What is the sense of touch?
This neurotransmitter is associated with mood regulation
What is the job of serotonin?
This lobe of the brain is primarily involved in hearing and language comprehension.
What is the temporal lobe?
This condition causes tremors and rigidness, and is typically caused by a lack of dopamine.
What is Parkinson's Disease?
The nervous system that controls the "fight or flight" response, preparing the body for stressful situations. Triggers the stress response hormones.
What is the sympathetic nervous system?
This is the minimum amount of stimulus energy needed to detect a stimulus.
What is the absolute threshold?
These cells support the cells located in the central nervous system.
What are glial cells?
The brain's ability to reorganize itself by forming new neural connections, especially as a response to an injury.
What is neuroplasticity?
a sudden, brief episode of muscle weakness or paralysis triggered by strong emotions, such as laughter, excitement, surprise, or anger.
What is cataplexy?
This almond-shaped structure located in the temporal lobe of the brain is involved in emotional regulation, memory, and motivation.
What is the amygdala and what is its function?
This phenomenon occurs when the brain fills in gaps that it lacks with visual information, such as when we can know what objects are even when they are partially obscured from our vision.
What is perceptual filling-in?
