Neuroscience Sudden Death Quiz - Statistics

Central Nervous System (CNS) consist of the brain and the spinal cord

Efferent nerves responsible for carrying sensory information to the brain and enters the spinal cord through the dorsal horn

The parasympathetic nervous system drive the "fight-or-fight" response

The cut along the plane that divides the brain into left and right halves called a sagittal section

Pirates wear eye patches as a practical tool for dark adaptation, allowing them to maintain one eye in a constant state of readiness for low-light conditions

Schwann cell are the glial cell that myelinates axons in the peripheral nervous system

Epigenetics is the inherited DNA sequence an organism carries, regardless of how it is expressed

The fovea is the region of the retina with the highest density of cones and the greatest visual activity

Frequency coding is the neural mechanism that uses the rate (frequency) of action potential firing to encode the intensity of a stimulus

Transduction is the process by which sensory receptor cells convert physical energy (light, sound, chemical) into electrical signals

Genotype is the study of heritable changes in gene expression that do NOT involve changes in the DNA sequence itself, including mechanisms like DNA methylation and histone modification

Corpus Callosum is the main commissure connecting the left and right cerebral hemispheres

Working memory refers to the system of memory that holds and manipulates information in conscious awareness over short periods; it includes a phonological loop and visuospatial sketchpad

Botox affects the acetycholine system by blocking nicotinic receptors on muscle cells

Multiple scierosis is a disease characterized by permanent depolarization of motor neurons

Broca's area and Wernicke's area are found in the right hemisphere

Myelin sheath stores neurotransmitters for release at synapses

Dopamine is primarily associated with the reward pathway and the four dopaminergic pathways

Patient H.M. had most of his hippocampus removed bilaterally to treat severe epilepsy and became one of the prominent cases in neuroscience

Basal ganglia is responsible for emotional fear conditioning

Hippocampus is responsible for the episodic autobiographical memory

Amygdala is responsible for the formation of new declarative memories

Sound is a longitudinal wave and its pitch corresponds to the physical property of frequency

"Cortical magnification" refers to the cortex is larger in humans than in other animals

Astrocytes are the type of glial cell is responsible for myelination in the central nervous system

Occipital lobe is primarily responsible for processing visual information

An action potential is a specific change in membrane potential

Agonists dampen the effects of a given neurotransmitter

Black Widow Spider Venom is an indirect ACh agonist and can be deadly

Cocaine is a direct monoanime agonist

Upper motor neurons have cell bodies in spinal cord and axons which actually cause contraction of muscles

Caffeine is an indirect acetylcholine agonist
