The superior colliculus (upper hill) coordinates eye movement. Normally the eye moves around, looking here and there but at times is drawn to a spot on "the map". This is a 3-D map a person has put together. This spot is something of interest. The brain thinks it might be "danger". Many other species have this same colliculus.
What else can I help you with?
What are neurons that relay impulses from sensory to motor neurons?
Sensory Neurons
Does the hypothalamus relay sensory inputs?
No, the thalamus relays sensory inputs, not the hypothalamus.
Are neurons that relay impulses from sensory neurons to motor neurons?
Sensory Neurons
What is the major relay station for sensory information ascending to primary sensory areas of the cerebral cortex?
The thalamus is the major relay station for sensory information ascending to the primary sensory areas of the cerebral cortex. It receives sensory input from various parts of the body and relays this information to the appropriate cortical areas for further processing and interpretation.
How many synapses occur in this reflex arc?
In a simple reflex arc, there are typically three neurons and two synapses. The sensory neuron carries the signal from the receptor to the central nervous system, where it synapses with the interneuron. The interneuron then synapses with the motor neuron, which carries the signal to the effector organ to produce a response.
What are relay neurons?
An interneuron (also called relay neuron, association neuron, connector neuron or local circuit neuron) is a neuron that forms a connection between other neurons. Interneurons are neither motor nor sensory.
What is the function of the sensory organ?
Meissner's corpuscles; pain and touch receptors, Pacinian corpuscles; pressure receptors, hair follicle receptors; light touch receptors, Rufini's corpuscles; respond to deep pressurethat recieve the stimulus
What part of the brain acts a relay station for incoming sensory information?
cerebellum
What part of the brain receives sensory info and relay it to the cerebral cortex?
thalamus
Important relay station for sensory impulses traveling to the somatic sensory area in the post central gyrus encloses the third ventricle?
The 'Thalamus'
What is the relay and processing centers for sensory information?
The relay and processing centers for sensory information in the brain are primarily the thalamus and cerebral cortex. The thalamus acts as a gateway, relaying sensory information to the appropriate areas of the cortex for further processing and interpretation. The cerebral cortex then integrates and analyzes the sensory information to create our perception of the world around us.
What brain area is the relay center for all sensory information except one?
The thalamus is the relay center for all sensory information except for olfaction (the sense of smell). It processes and transmits sensory information to the appropriate areas of the cerebral cortex for interpretation. Each sensory modality has specific thalamic nuclei that handle its information before it reaches the cortex.
