Does "sleeping on it" improve decision making?
Although the science isn't completely conclusive, recent research suggests that sleep can, in fact, improve problem solving.
A 2018 study from the University of Bristol looked at a group's performance on mental tasks before and after taking a 90 minute nap. When compared with a group that stayed awake for the same amount of time, the nappers did markedly better on their repeated task, which indicated to the researchers that the brain did process some of that information as they slept.
Keep in mind, though, that with only 16 participants, more studies are needed to be able to confidently generalize these specific results. More broadly, sleep has been widely proven to help with memory, learning, and judgement, which will all come in handy the next time you have to make a difficult decision.Similarity between shark brain and human brain?
"One of the papers shows that with great white sharks, the area of the brain that receives visual input is quite large, and suggests the relative importance of vision in these animals is quite high," she said.
"This information may direct researchers' efforts towards targeting the visual system when developing repellants for sharks," she added.
Another paper suggested the cerebellum - which controlled motor movement and appeared first in early sharks - was an important evolutionary advancement that led to aspects of higher neural function in vertebrates including humans, Yopak said.What in a person's brain and body gives them their unique natural talents and abilities?
its not their brain. its in their genes, their DNA. If it's in the genes (both parents) then it doesn't explain the fact of a person that is a genius when neither parent is. I have a girlfriend who has 3 children all in their mid-30s now, and all are bright individuals, but her one son is a genius and has made a great deal of money because of it. As my girlfriend says "I have no idea where he got THAT from!" I don't believe it's a "throw-back" to ancestors or you would have heard of it by now. I think it's simply unexplainable.
What are the cells of the brain?
The brain is composed of two types of cells, neurons and glial cells.
What lobes of the cerebrum are visible in midsagittal section?
The frontal and occipital lobes of the cerebrum are visible in midsagittal section.
What are the major structures in a crustacean?
I am going to assume you are talking about decapod crustaceans, which is the kind most people eat. You can imagine a lobster as I describe the parts, but the description applies generally to all decapods, even crabs. The animal is covered by a chitinous exoskeleton. The shell that makes up the head is called a carapace, and it covers both the animal's head and thorax (similar to your torso). The head and thorax in a lobster have been fused together to form a cephalothorax. The part most people call a tail is actually the abdomen of the animal. Now I'll describe the main appendages on the animal going from front to back. In front, there are 10 walking legs (5 on each side), called pereiopods (pereio = thorax, pod = leg or foot). Usually, at least the first pair are modified at the tips to form chelae(claws). These are always attached to the cephalothorax. There are also appendages attached to the bottom of the abdomen, called pleopods (pleo = abdomen, pod = leg or foot). At the very end of the tail, there are additional flattened appendages which make up the tail fan. The flattened portion are called uropods (uro = tail). The center piece, flat in lobsters, a sharpened tip in shrimp, is called the telson. Crabs are constructed more or less the same way except the abdomen is greatly reduced and folded under the cephalothorax (check it out next time you are eating a crab!).
cerebral palsy.
Can people die from brain freeze?
No it is not humanly possible for a person to die from a brain freeze.If you could die from a brain freeze the population of people would decrease every second of the day.Someone in the world is having a brain freeze right now but i dont actually think they are dying.
What brain structure is involved in creating new explicit memories?
Several structures in the brain are thought to be involved in explicit memory. Most are in the temporal lobe, amygdala, the hippocampus, and the prefrontal cortex. Nuclei in the thalamus also are included.
What is dementia in the brain?
Dementia is a syndrome (a group of related symptoms) that is associated with a progressive decline in mental functions and abilities. For example: * memory, * thinking, * language, * understanding, and * judgement. People with dementia may also have problems controlling their emotions, experience changes in their personality, and behave inappropriately in social situations. Most cases of dementia are caused by damage to the structure of the brain. See the NHS Direct related link for more info.
it smells slightly strange but its not a bad smell, it doesn't smell like poo at all. It has a slight tinge of smell to it but its not bothering unless you don't like the smell of, say , limestone.
Hypothalamus, it links the nervous system to the endocrine system via the pituitary gland (hypophysis).
P.S. - It secretes hypothalamic tropic factors (hypothalamic hormones - neurohormones, often called hypothalamic-releasing hormones) to the anterior lobe of the pituitary gland by way of a special capillary system, called the hypothalamic-hypophysial portal system.(Courtesy: Wikipedia - the free encyclopedia)
Are the causes of stress different for boys and girls?
boys are different to girls but I think that the causes are similar
What happens if parietal lobe is damaged?
Well, the parietal lobe has to do with sensory (ability to feel touch), and pain
so, i guess that you wouldn't be able to feel when someone touches you, or hits you. (again if you noticed i put i Guess)
hope this helps (hopefully my Psychology teacher feels proud)
Why superficial reflexes are lost in upper motor neuron lesion?
because the superficial reflex fibres also come through the umn fibres along with it
The blood-brain barrier shields brain cells from toxins by?
The blood brain barrier (BBB) is composed of a high concentration of endothelial cells in the brain's capillaries, which help to prevent toxins from passing into the brain from the blood supply.
What are the 5 parts of the brain?
frontal, temporal, occipital, parietal, and then there's the cerebellum.
What structure will be seen connecting the two lobes of the thalamus?
In about 70% of the people the thalamus is connected to each other by Interthalamic adhesion (massa intermedia, middle commissure, gray commissure).
What does a venous angioma int he right frontal lobe without hemorrhage mean?
It means you have a vein malformation. I suffered my first seizure ever three days ago. Admitted to hospital, MRI with contrast and EEG showed my venous angioma is in the frontal lobe of my brain. I am now on anti-seizure medication and will have a new MRI and EEG every three months to make sure there are no changes.
Why can't son swallow after brain surgery?
I think because it does something to the brain when it goes through the nervous system so it blocks out your throat systems(?) And also because you just had brain surgery so it's most likely that your brain is controlling every part of your body!
