Origins
This ancient surgical practice involved cutting a hole in the skull and has been found on every inhabited continent.
What is trepanation (trepanning)?
The part of the neuron that takes information away from the cell body.
What is the axon?
The mode through which a neuron transports electrical signal, causing a neuron to depolarize/gets less negative
What is an action potential?
This term describes a structure on the same side of the brain as a reference point.
What is ipsilateral?
This lobe is posterior to the parietal lobe
What is the occipital lobe?
This view asks whether different brain regions perform different specific functions.
What is localization of function?
This is the gap between two neurons, across which they communicate.
What is a synapse?
This refers to when a membrane potential at rest becomes more negatively charged
What is hyperpolarization?
This axis marks the relative position of the parietal and frontal lobe.
What is the anterior-posterior axis?
This lobe sits anterior to the central sulcus and is home to the primary motor cortex.
What is the frontal lobe?
The view that the brain acts as an undifferentiated whole.
What is mass action (equipotentiality)?
Myelin is produced by these cells and increases the speed at which electrical signals travel down the axon.
What are oligodendrocytes?
The difference in the charge inside vs. outside the neuron when the neuron is “at rest” = about -70 mV.
What is a resting membrane potential?
The spinal cord is on this side of the body relative to the nose.
What is posterior (or dorsal)?
This lobe, located inferior to the lateral fissure, is associated with auditory processing.
What is the temporal lobe?
Franz Joseph Gall's theory that skull bumps reveal a person's mental 'faculties' is known by this name.
What is phrenology?
This addition to the axon allows neurons to conduct action potentials at a greater speed through saltatory conduction.
What is the myelin sheath?
Movement of this ion inhibits a neuron
What is a chloride (Cl-) ion?
A lesion affecting only one side of the brain is described by this term.
What is unilateral?
This lobe is posterior to the frontal lobe and anterior to the occipital lobe.
What is the parietal lobe?
This physician observed that seizures beginning in the hand traveled up the arm
Who is Hughlings Jackson?
Opening of this channel creates the rising phase of an action potential
What are voltage-gated sodium channels?
This is the name of a molecule produced and released by a pre-synaptic neuron that has direct influence on the physiology of a post- synaptic cell.
What are neurotransmitters?
Motor control of the right hand is primarily managed by neurons on this side of the brain.
What is the left (contralateral) side?
This lobe, located at the back of the brain, is the primary destination for visual information arriving from the LGN via V1.
What is the occipital lobe?
