Human Brain

Human Brain !!!

Do you know our brain is so much beyond our understanding.
There are so many conditions whose dysfunctioning can lead to various funny results...

Prosopagnosia : Inability to recognize face - seen in inferior temporal lobe lesion.

Acalculia : Inability to solve mathematical problems - seen in frontal lobe lesion.

Navigation defect : Inability to localise place and inability to move at the place - seen in lesion of Right hippocampus and right caudate lobe.

Agnosia : Inability to recognise objects even when our sensory receptors and sensory nerves are intact - seen in lesion of parietal lobe

Deja vu : In this person feels as if future incident has already seen by him.e.g.you will feel while driving that you have already seen this phase of time beforw that you were driving and listening this particular song.-seen in temporal lobe epilepsy as well as many times normally in humans.

Hemi inattention and neglect : Ignoring and avoiding stimulus from half of the body.for e.g. wearing clothes on half side,shaving,brushing on half side,reading half paper...- seen in inferior parietal lobe lesion.

Lesion in amygdala - Inability to encode emotions associated with memories

Lesion in hippocampus - loss of antegrade memories

And you know our body is projected on brain cortex vertically and from upside down.Means legs are projected on top and face and head at bottom of cortex.

And the more the part of body you use its projection area in brain is more wider and stronger.e.g.If you are writer your palm area in brain will be stronger.if you are speaker or singer your speech area in brain will be stronger.
