What is a hypo dense lesion on the brain?
a hypodense lesion is any lesion in the brain of density lesser than the normal tissue.it can be any fluid collection such as pus, blood or cyst or any low grade tumors with cystic changes.occipital region is a region in the backside of the brain. so hypodense lesion in occipital region denotes any of the above lesions in that region.to find out the exact lesion clinical correlation is needed.
What part of the brain are associated to schizophrenia?
None, because schizophrenia is a condition determined by checklists and psychiatrists. It is not a condition derived from physical brain damage.
What does brain teaser timing Tim ing mean?
"Brain teaser timing" refers to the speed and accuracy with which an individual solves brain teasers or puzzles. It involves the ability to quickly analyze and process information to arrive at the correct solution within a given time frame. Improving brain teaser timing can enhance cognitive skills such as problem-solving, critical thinking, and decision-making.
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.
What are 4 main parts of the limbic system?
Cingulate gyrus, hippocampal formation, amygdala and septum
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)
Cerebral Cortex
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.
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
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.
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.
