15 Questions
What is the main function of Broca's area in the brain?
Motor control of speech
What is the difference between ionotropic and metabotropic receptors?
Ionotropic receptors cause a rapid, short-lived response, while metabotropic receptors cause a slower, longer-lasting response.
What is the main function of the blood-brain barrier?
To prevent the entry of foreign substances into the brain
What is the difference between resting potential and Nernst potential?
Resting potential is the potential difference required to balance the concentration gradient of a single ion, while Nernst potential is the potential difference across the membrane when no ions are flowing.
What is the function of the axon hillock in a neuron?
To integrate incoming signals and generate an action potential
What is the main difference between grey and white matter in the brain?
Grey matter contains cell bodies while white matter contains axons and dendrites.
What is the fallacy of phrenology?
The idea that specific personality traits can be determined by the shape of the skull.
What is the main function of Broca's area in the brain?
Speech production.
What is the difference between ionotropic and metabotropic receptors?
Ionotropic receptors directly open ion channels while metabotropic receptors activate second messenger systems.
What is the main difference between excitatory and inhibitory synapses?
Excitatory synapses increase the likelihood of an action potential while inhibitory synapses decrease the likelihood of an action potential.
What is the main difference between grey and white matter in the brain?
Grey matter contains cell bodies while white matter consists of axons and myelin
What is the fallacy of phrenology?
The belief that personality traits can be determined by the shape of the skull
What is the role of the blood-brain barrier?
To protect the brain from harmful substances in the bloodstream
What is the difference between ionotropic and metabotropic receptors?
Ionotropic receptors directly open ion channels while metabotropic receptors activate second messenger systems
What is the difference between temporal and spatial summation in neuronal signaling?
Temporal summation involves multiple signals from the same neuron over time while spatial summation involves signals from multiple neurons at the same time
