Neuroanatomy
NTs & drugs
Sensation
Action potentials & synaptic transmission
Pathologies
100
This structure processes conditioned fear responses
Amygdala
100
The #1 excitatory NT in the brain
Glutamate
100
The only sensory modality that does not route through the thalamus before reaching the primary sensory cortex
Olfaction
100
The conduction of an action potential in a myelinated neuron ("jumping" AP)
Saltatory conduction
100
This drug is used to treat bipolar disorder and shares a name with a popular Nirvana song
Lithium
200
Name the structure your Jeopardy host is point to in the image:
What is the corpus callosum?
200
This NT is present at the NMJ and is required to facilitate movement.
Acetylcholine
200
This mechanoreceptor is responsible for detecting deep pressure and vibration.
Pacinian corpuscle
200
The point at which the charge of a neuron is below resting potential (~-70)
hyperpolarization, hyperpolarized neuron
200
This type of amnesia is characterized by the inability to form new memories.
Anterograde amnesia
300
This structure on the neuron is where saltatory conduction occurs
Node of Ranvier
300
This enzyme breaks down dopamine, norepinephrine, and serotonin.
Monoamine oxidase
300
This photopigment is involved in signal transduction in visual processes (especially in the periphery of the visual field)
Rhodopsin
300
The type of potential that decreases the likelihood of a neuron firing an action potential
IPSP or inhibitory postsynaptic potential
300
Alterations in brain structure, such as misaligned hippocampal cells, enlarged ventricles, and tissue loss, are characteristics of this psychological disorder
Schizophrenia
400
Striate cortex or primary visual cortex
400
This drug increases the activity of monoamine NTs, prolonged & frequent use of this drug is likely to result in drug-induced psychosis and formication (skin-picking)
Amphetamine/methamphetamine
400
After optic nerve fibers cross the optic chiasm, they pass through this region within the thalamus.
Lateral geniculate nucleus (LGN)
400
These two processes facilitate the movement of ions across a semi-permeable membrane (phospholipid membrane)
1. Electrostatic pressure
2. Diffusion
400
This condition is characterized by the inability to perceive moving objects
Akinetopsia
500
What structure is highlighted in red in this diagram?
Inferotemporal cortex
500
These drugs can cause undesirable side effects such as Parkinsonian symptoms and tardive dyskinesia
First-generation antipsychotics
500
This condition is characterized by the lack of coordination between visual input and motor responses (a woman tries to grab a waterbottle but is unable to successfully grab it)
Optic ataxia
500
The 3 processes through which a neurotransmitter leaves the synapse
1. Reuptake
2. Enzymatic degradation
3. Diffusion
500
Taenia Solium (aka Tanya) is a pathogen involved in the development of which neurological condition (lays eggs in the brain)
Neurocysticercosis
