People often sneeze without any unhealthy medical cause.Sometimes we don't have cold but still we sneeze.There can actually other reasons to have sneeze and there are some interesting facts about sneeze.Some of them you may already know but some will get you amazed.Here is countdown.... 1.Superfast Sneeze:- Sneeze can travel upto 100 miles per hour.Yeah really... 2.Without blink sneeze:- It is quite amazing that you can't sneeze without closing your eyes.If you don't believe it then next time when you sneeze keep that in mind and try to sneeze with your eyes open. 3.Sneeze coz of Sunlight:- It is found in studies that bright light can make you sneeze. About one in four people sneeze in sunligh...

1. Dolphins can sleep with one-half of their brain active.Do you understand what does that mean...They can remain alert while sleeping. They can have the brain waves of non-REM sleep functioning in just one hemisphere while the other half remains awake.Whales also can do the same.And Dolphin also holds the title of the most smart fish ever known.
Accuracy of visual memory Visual Memory Visual memory is recollected information about what one has seen. It involves both the mental storage of such information and the ability to retrieve it. The recalled image of a sunset, the memory of a font type, the remembrance of a tree's appearance: these are all instances of visual memory. Psychologists refer to visual memory to help account for memory in general. It is distinct from other kinds of memory, such as auditory memory (recollection of what one has heard). Some researchers believe visual memory plays an important role in learning. For example, some learning disabilities (including dyslexia) are linked to poor visual memory, such as the inability to remember the sequence of letters in words.
Formation of OLfactory Memory Introduction Olfactory Memory refers to the memory associated with odors and smells.If you just spare your 5 minutes in thinking that how our brain can memorise a smell which does not even seem to be a material thing then you'll get confused.Visual memory is associated with pictures, Echoic Memory is associated with sounds but both pictures and sounds can be stored as coded information but SMELL...! How memory of smell can be stored.To understand the structure of formation of olfactory memory we'll discuss each step through which the information is passed.
This article is about to reduce headache in our stressful life Headaches and stress is very often among the new generation.People get stressed-out on normal issues which leads to their poor mental health and tensed life.There is not a magical wand which can just flew away all the tensions of our life but we can adopt some ways by means of which we can reduce our stress instead of reducing our life-span.
Function The thalamus has multiple functions. It may be thought of as a kind of switchboard of information. It is generally believed to act as a relay between different subcortical areas and the cerebral cortex . In particular, every sensory system (with the exception of the olfactory system ) includes a thalamic nucleus that receives sensory signals and sends them to the associated primary cortical area. For the visual system, for example, inputs from the retina are sent to the lateral geniculate nucleus of the thalamus, which in turn projects to the visual cortex in the occipital lobe . The thalamus is believed to both process sensory information as well as relay it—each of the primary sensory relay areas receives strong feedback connections from the cerebral cortex Similarly the medial geniculate nucleus acts as a key auditory relay between the inferior colliculus of the midbrain and the primary auditory cortex, and the ventral posterior nucleus is a key somatosensory relay, w...
Amygdala Amygdala are almond-shaped groups of nuclei located deep and medially within the temporal lobes of the brain in complex vertebrates, including humans.[2] Shown in research to perform a primary role in the processing of memory, decision-making, and emotional reactions, the amygdalae are considered part of the limbic system.
HEADACHE A headache or cephalalgia is pain anywhere in the region of the head or neck. It can be a symptom of a number of different conditions of the head and neck. The brain tissue itself is not sensitive to pain as it lacks pain receptors . Rather, the pain is caused by disturbance of the pain- sensitive structures around the brain. Nine areas of the head and neck have these pain- sensitive structures, which are the cranium (the periosteum of the skull), muscles, nerves , arteries and veins , subcutaneous tissues , eyes, ears , sinuses and mucous membranes . There are a number of different classification systems for headaches. The most well-recognized is that of the International Headache Society. Headache is a non-specific symptom, which means that it has many possible causes. Treatment of a headache depends on the underlying cause, but commonly involves pain killers .
CEREBRAL CORTEX Functional Divisions of the Cerebral Cortex The cerebral cortex is responsible for many "higher-order" functions like language and information processing. Language centers are usually found only in the left cerebral hemisphere. For more information on language and differences between the right and left cerebral hemisphere, read about split brain experiments.
How Does Brain Plasticity Work ? The human brain is composed of approximately 100 billion neurons. Early researchers believed that neurogenesis, or the creation of new neurons, stopped shortly after birth. Today, it is understood that the brain possesses the remarkable capacity to reorganize pathways, create new connections and, in some cases, even create new neurons.
Neuroplasticity , also known as brain plasticity , is an umbrella term that encompasses both synaptic plasticity and non-synaptic plasticity—it refers to changes in neural pathways and synapses which are due to changes in behavior, environment and neural processes, as well as changes resulting from bodily injury.
