Where does the second pathway of visual information go before it goes to the cortex?
The second pathway of visual information, known as the "where" pathway or the dorsal stream, primarily projects from the primary visual cortex (V1) to the parietal lobe. This pathway processes spatial awareness and motion, helping to determine the location and movement of objects in the visual field. Before reaching the cortex, visual information travels from the retina to the lateral geniculate nucleus (LGN) of the thalamus and then to V1.
What else can I help you with?
What is the minimum number of neurons required to carry information from a sensory receptor to the somatosensory cortex?
At least three neurons are required to carry information from a sensory receptor to the somatosensory cortex. The first neuron is located in the sensory receptor, the second neuron is in the spinal cord or brainstem, and the third neuron is in the thalamus before reaching the somatosensory cortex.
The second order neuron of the spinothalamic system terminates at?
The second-order neuron of the spinothalamic system terminates in the thalamus, specifically the ventral posterolateral nucleus. From here, the information is relayed to the somatosensory cortex for further processing and perception of pain and temperature.
The parietal lobe has two jurisdictions one is the motor cortex and the other is the what which receives signals from the touch senses?
The parietal lobe's second jurisdiction, alongside the motor cortex, is the somatosensory cortex. This area is responsible for processing sensory information related to touch, temperature, pain, and proprioception from various parts of the body. It allows us to perceive and interpret tactile stimuli, contributing to our sense of body awareness and spatial orientation.
Second order neurons of both specific and nonspecific ascending pathways terminate where?
Second order neurons of both specific and nonspecific ascending pathways terminate in the thalamus. From there, the thalamus sends projections to the somatosensory cortex for further processing of sensory information.
What is the name of the second cranial nerve which provides a pathway from retina to brain?
The second cranial nerve is called the optic nerve. It carries visual information from the retina at the back of the eye to the visual centers in the brain, allowing us to process and interpret visual stimuli.

Where do Ascending sensory neurons terminate?
Ascending sensory neurons primarily terminate in the spinal cord and brainstem, where they synapse with second-order neurons. These second-order neurons then project to various brain regions, including the thalamus, which relays sensory information to the appropriate areas of the cerebral cortex for processing. The precise termination points can vary depending on the specific sensory pathway involved, such as the dorsal column-medial lemniscal pathway or the spinothalamic tract.

By Anaerobic pathway of glucose break down.(Glycolysis.)

What are the structures for the pathway of a secondary oocyte?
In what order does the pathway of a second Oocyte ampulla of uterine, body of uterus, fimbriae of uterine tube, fundus of uterus, infundibulum of uterine tube, isthmus of uterine tube and ovary
What is the role of the thalamus in hearing vision taste and smell?
It is the part of the brain whose function includes relaying sensation, special sense and motor signals to the cerebral cortex, along with the regulation of consciousness, sleep and alertness.It acts as a kind of railway signal box. As information comes in through the senses, it goes directly to the thalamus and it sends the signals off to different parts of the railway yard (brain). It will send the signal to the cortex, or rational part of the brain and to the limbic or emotional brain at the same time. Although the limbic system will react to the stimulus a lightning split second quicker than the cortex, often sending people into flight or fight when it's not really appropriate in the present circumstances.--1. Thalamus acts as a relay station for both afferent and efferent fibres of the cerebral cortex. ]2. Along with the hypothalamus, it helps in sleep and wakefullness.3. Along with the cerebellum & basal ganglia, it helps in maintaining body posture.The thalamus is a by-station from the sensory organs to the cerebral cortex sensory regions. It has a somatosensory mapping of the body and has known integrative functions.There is also a part of the brain called the hypothalamus. It is the "leader" of the endocrine system. It controls what and where the hormones do and go and when they go at a certain time---One of the functions of the thalamus is to relay sensory information by transmitting axons to other regions of the cerebral cortex. Such as: the sense of touch is relayed to the parietal lobe, the sense the sight is relayed to the occiptal lobe, the sense of hearing is relayed to the temporal lobe, and the sense of balance is relayed to the cerebellum. The thalamus does NOT relay the sense of smell to the temporal lobes though.---The thalamus is the gateway to the brain that is responsible or receiving almost all incoming sensory information before the information reaches the cortex. Axons from every sensory system, except for olfaction, synapse in the thalamus as a last pit stop before the information reaches the cerebral cortex.The functions of the thalamus include relaying sensory and motor signals to and from the cerebral cortex, regulating consciousness, sleep, and alertness.The thalamus is a by-station from the sensory organs to the cerebral cortex sensory regions.

The thymus increases gradually in size and activity until puberty, becoming vestigial thereafter.It relays information from different parts of the brain.it is part of your brain. it is the relay for sensory impulses. it shows what is pleasant and unpleasant.The thalamus is a major relay center. All incoming sensory information except smell goes through the thalamus, before reaching the cerebral cortex. (And even smell has a pathway connecting to the thalamus.) The actual processing of the sensory information starts here, this is especially true about vision. It also participates in the regulation of sleep, arousal and wakefulness, and plays a role in motor functions as well.
