The
cerebral cortex
is connected to various subcortical structures such as the thalamus and the basal ganglia. Most sensory information is routed to the cerebral cortex via the thalamus.
Which part of the central nervous system sorts almost all of the ascending sensory information?
1. Which part of the CNS sorts almost all of the ascending sensory information?
Thalamus
. Afferent impulses from all senses and all parts of the body converge on the thalamus and synapse with at least one of its nuclei.
Which part of the brain sorts out the majority of the ascending sensory information?
The thalamus–
which sorts out and “edits” these afferent signals before relaying them to the appropriate cortical areas–is considered to be the gateway to the cerebral cortex.
Which area of the brain receives almost all sensory information first?
The thalamus
is often described as a relay station. This is because almost all sensory information (with the exception of smell) that proceeds to the cortex first stops in the thalamus before being sent on to its destination.
What part of the brain is the executive suite?
“Executive suite”: The cluster of functions that
center in the prefrontal cortex
is sometimes called the “executive suite,” including calibration of risk and reward, problem-solving, prioritizing, thinking ahead, self-evaluation, long-term planning, and regulation of emotion.
What part of the brain controls the 5 senses?
The parietal lobe
gives you a sense of ‘me’. It figures out the messages you receive from the five senses of sight, touch, smell, hearing and taste. This part of the brain tells you what is part of the body and what is part of the outside world.
How does sensory information travel to the brain?
Ascending pathway to the brain: Sensory information
travels from the body to the spinal cord before reaching the brain
. This information ascends upwards using first, second, and third-order neurons. … Second-order neurons live in the dorsal horn and send impulses to the thalamus and cerebellum.
What part of the brain controls the central nervous system?
The pons and the medulla, along with the midbrain, are often called the
brainstem
. The brainstem takes in, sends out, and coordinates the brain’s messages. It also controls many of the body’s automatic functions, like breathing, heart rate, blood pressure, swallowing, digestion, and blinking.
What part of the brain is responsible for body orientation and eye movements?
The prefrontal cortex
plays an important part in memory, intelligence, concentration, temper and personality. The premotor cortex is a region found beside the primary motor cortex. It guides eye and head movements and a person’s sense of orientation.
Which ascending sensory pathway is associated with balance?
The vestibulospinal tract connects the brain stem nuclei of
the vestibular system
with the spinal cord. This allows posture, movement, and balance to be modulated on the basis of equilibrium information provided by the vestibular system.
What are the 4 motor areas of the cerebral cortex?
These areas are the primary motor cortex (Brodmann’s area 4),
the premotor cortex, and the supplementary motor area
(Figure 3.1).
What are the 3 functional areas of the cerebral cortex?
As a means of simplification, the cerebral cortex is often characterized as being made up of three types of areas:
sensory, motor, and association areas
.
What are the sensory areas of the brain?
The primary sensory areas (
visual, auditory, somatic sensory and gustatory areas
) receive information from peripheral receptors with only a few synapses interposed. The primary visual cortex is located at the caudal pole of the occipital lobe, mainly on its medial region.
What part of the brain controls memory?
The prefrontal cortex holds recent events briefly in short-term memory.
The hippocampus is responsible for encoding
long-term memory. Short-term memory, also called working memory, occurs in the prefrontal cortex. It stores information for about one minute and its capacity is limited to about 7 items.
Which part of the brain is most strongly associated with executive functions?
Executive functions are located primarily in
the prefrontal regions of the frontal lobe
of the brain with multiple neuronal connections to other cortical, subcortical and brainstem regions.
What part of the brain is the executive suite that controls almost all brain activity?
Which part of the brain is the “executive suite” that controls almost all brain activity?
The cerebral cortex
is the “executive suite” of the nervous system, where most of our higher-level decision making occurs.
