Why doesn't damage in the right visual cortex result in blindness of the right eye?
The right side of the brain controls the left side of the body. Also the optic nerves cross over when they leave the eyes.
A homunculus is the nerve map of the human body which exists on the parietal lobe of the brain.
When does the spirit leave the body when a per son is brain dead?
Never. Research done at my local institution claims that in order for the soul to properly be freed from the human body, ALL organs must no longer function. So unless the person is completely dead, the soul will remain intact. Though, some believe that the soul leaves when the heart stops.
Cerebral Cortex
What happens to brain at high altitudes?
Alarming new science shows that thin air can wreck brain cells-at lower altitudes than you'd think.
Is the left part of your brain smarter that your right part of your brain?
No, they just seem to control different things, the left side is your more structured/listed items, the right is your more artistic side (thinking outside of the box)
What are 4 main parts of the limbic system?
Cingulate gyrus, hippocampal formation, amygdala and septum
Which portion of the human brain mediates simple reflexes such as sneezing coughing and salivating?
The medulla oblongata is a part of the brain stem involved in these reflexes. And no your eyes will not pop out if you sneeze with them open. Closing the eyes is part of the reflex and you have no control over reflexes.
What part of the brain is mainly responsible for writing?
The part of the brain that helps us to write is the cerebellum.
Do our brains run on binary code?
Lets just say nobody knows how the brain works deep deep down. But there are binary things in the brain, like a neuron will either output a 1 (it fires) or a zero (it does nothing) depending on the number of electrical pulses sent to the neuron
The falx cerebri is the fold of dura mater that divides the right and left hemispheres of the brain.
Why does sense of smell bypass the thalamus?
I found this info:
Does anything about this system strike you as odd? The olfactory system disobeys a general rule of sensory systems - it does not have to pass through thalamus before reaching cortex. However, there is a very good reason why not; olfactory cortex is an old and primitive structure, and in fact has only four cellular layers, unlike the 6-layered cortex we are accustomed to. The rule that sensory information must pass through thalamus to get to cerebral cortex is still true, but only for 6-layered cortex, or neocortex. This description applies to almost every area in the frontal, parietal, occipital, and temporal lobes.
It also seems like the olfactory bulb does a lot of the processing and sends sensory info directly to the olfactory cortex.
Do headphones cause brain damage?
headphones don't cause brain damage but they can cause deafness because of the radiation.its better to be loud speaker rather than using headphone...
Can propafanone help with serotonin?
The medication propafanone is prescribed for illnesses that have a rapid heartbeat. There is no data that states or links propafanone with serotonin at this time.
When the body receives stimuli which structure typically processes the stimuli?
The brain processes sensory stimuli.
Does the brainstem help you taste things?
no it doesnt but i'm pretty sure the cerebrum ( the big squishy part ) is the one that helps you taste
That would be the 'Occipital Lobe' it is the visual part of the brain.
The hypothalamus is like your brains inner thermastat ..?
The hypothalamus is located below the thalamus and above the brain stem. Its functions are controlling body temperature, hunger, thirst, sleep, and circadian rhythms.
the portion of the brain, consisting of the medulla oblongata and midbrain, that connects the spinal cord to the forebrain and the cerebrum. Included in the brainstem is the diencephalon, midbrain, pons and the medulla oblongata.It is the oldest part of the brain.
A brain scanner is, quite simply, a device used to scan (image) the brain. In the recent decades, we have advanced medical technology through applied physics to spawn a variety of medical imaging equipment. And imaging has really bloomed. We want to look at the structure of the brain as a guide to treatment of injury or disease as well as for research. The term brain scanner has fallen by the wayside because there are several different methods of imaging the skull and its contents. Each has advantages and disadvantages, and it preferred or avoided in a given investigation. We normally specify the type of imaging we are going to do. We may need a cranial X-ray or we may want a magnetic resonance imaging (MRI) picture to look at what's going on inside someone's head. Perhaps a PET scan (positron emission tomography) is ordered by a physician.
Why does the brain have a semi permeable brain?
The semi permeable membrane is called the blood brain barrier. It allows smaller molecules such as oxygen to enter the brain, and also protects the brain by preventing larger molecules such as toxins to enter.
