insensitve to visual stimulation, the part of the retina where the axons of the ganglion cells converge to form the optic nerve . the area of the retina where axons from ganglion cells meet to form the optic nerve.
Where is sensory information processed in the brain?
The parietal lobe is located in the middle section of the brain and is associated with processing tactile sensory information such as pressure, touch, and pain. A portion of the brain known as the somatosensory cortex is located in this lobe and is essential to the processing of the body’s senses.
– The optic nerve conducts sensory input to the visual area of the occipital lobe.
What is the sense that informs you about the position and motion of parts of the body?
Kinesthesis is the sense of the position and movement of body parts. Through kinesthesis, people know where all the parts of their bodies are and how they are moving. Receptors for kinesthesis are located in the muscles, joints, and tendons.
What is best described as the stimulation of sensory receptors and the transmission of sensory information to the central nervous system?
Sensation & Perception Sensation : The stimulation of sensory receptors and the transmission of sensory information to the central nervous system. ... Perception : The process by which sensations are organized into an inner representation of the world. A psychological process.
Which effect would someone with damage to the occipital lobe most likely display?
An injury to the occipital lobes can lead to visual field cuts , difficulty seeing objects or colors, hallucinations, blindness, inability to recognize written words, reading or writing, inability to see objects moving, and poor processing of visual information.
Is the area where sensory information gets processed?
Thalamus : The thalamus is the relay center of the brain. It receives afferent impulses from sensory receptors located throughout the body and processes the information for distribution to the appropriate cortical area.
How does brain process sensory information?
Information processing starts with input from the sensory organs, which transform physical stimuli such as touch, heat, sound waves, or photons of light into electrochemical signals. The sensory information is repeatedly transformed by the algorithms of the brain in both bottom-up and top-down processing.
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.
How does sensory information get processed?
All sensory signals, except those from the olfactory system, enter the central nervous system and are routed to the thalamus . When the sensory signal exits the thalamus, it is conducted to the specific area of the cortex dedicated to processing that particular sense.
What are the four basic touch sensations?
The thousands of nerve endings in the skin respond to four basic sensations — pressure, hot, cold, and pain — but only the sensation of pressure has its own specialized receptors. Other sensations are created by a combination of the other four.
What is the best example of sensory interaction?
Sensory interaction refers to the interaction of the senses to each other and how they influence each other. Taste and smell are two senses that work together. Food tastes more bland when a person has a stuffy nose and can’t smell it properly.
What is the process of becoming more sensitive to stimulation?
sensitization . or positive adaptation , the process of becoming more sensitive to stimulation the type of sensory adaptation in which we become more sensitive to stimuli that are low in magnitude. desensitization.
What is the function of the sensory receptors?
The sensory receptors transform external energies into changes in the membrane potential . All sensory receptors have some mechanisms in common, such as detection, amplification, discrimination, and adaptation.
What is the stimulation of sensory receptors in the transmission of sensory information to the brain?
Sensation is a mechanical process that involves the stimulation of sensory receptors (neurons) and the transmission of sensory information to the central nervous system. ... We know something is there when the intensity of the stimulus, such as a light, exceeds the absolute threshold for that stimulus.
What information does the brain use to determine the intensity of a stimulus?
How does the brain determine the intensity of a stimulus? By looking at the number of receptors activated and the frequency of action potentials from them . Also looks at the quality of the receptors that are activated. Receptors have different thresholds of activation – this can tell us how large the stimulus was.
