Neurotransmitters 1
High levels of this neurotransmitter result in excitotoxicity, or cell death.
What is glutamate?
The excitatory amino acid neurotransmitter.
What is glutamate?
The relay stations for sensory pathways.
What is the thalamus?
These cells respond to photons.
What are photoreceptors?
The area of the eye where there are no photoreceptors.
What is the blindspot?
Glutamates ionotropic receptors allow the passage of this ion.
What is sodium (Na+)?
Only the synthesis of small-molecule neurotransmitters require one of these.
What is a precursor?
The structure separating the somatosensory and motor cortices of the brain.
What is the central sulcus?
This muscle controls the shape of the lens.
What is the ciliary muscle?
The conversion of physical energy to an electrochemical signal that neurons can recognize.
What is transduction?
Caused by decreased acetylcholine at the neuromuscular junction.
What is paralysis?
The ionotropic receptor for acetylcholine.
What is nicotinic?
The outdated method of correlating bumps in the skull to personality.
What is phrenology?
Short-sightedness, or blurry vision caused by the eyeball being too long.
What is myopia?
These cells' axons make up the optic nerve.
What are ganglion cells?
When benzodiazepines bind to a receptor, they potentiate the effect of this neurotransmitter.
What is GABA?
This non-classical neurotransmitter's receptors are blocked by caffeine.
What is adenosine?
The area of the brain where the raphe nuclei begin.
What is the medulla oblongata?
The visual system that involves the cones, so requires more light and allows color vision.
What is the photopic system?
A part of the thalamus, specialized for visual information.
What is the lateral geniculate nucleus?
The monoamine, Serotonin, is of this type.
What is an indoleamine?
These precursor peptides are processed into smaller active opioid peptides.
What are propeptides?
These roots of the spinal cord contain motor neuron axons.
What is the ventral root?
When light hits these retinal cells, no action potential occurs in the optic nerve.
What are rods?
The inability to recognize faces due to ventral stream deficits.
What is prosopagnosia?
