This summary is founded on a video series, found on YouTube, depicting the findings of neurologist, Dr . V. S i9000. Ramachandran. Ramachandran is mentioned for his use of trial and error methods that rely comparatively little about complex solutions such as neuroimaging. According to Ramachandran, “too much of the Even victorian sense of adventure [in science] has been dropped. 

If the Dr . stroked the q-tip across the left side of the people face, the individual felt that same movement sensation around the missing correct hand. Dr . Ramachandran theorizes that the side of the body is mapped to the right side of the brain through a tape of emballage called the somatosensory cortex. When there is a missing limb, the part of the mind the compares to that limb no longer gets any suggestions.

The Dr . has learned that sensory indicators that, normally, only switch on facial senses, are now entering the left the space territory that corresponds to the missing side and activates the same sensations in the hand that are sensed on the face. This kind of research has proven that there have been a massive reorganization of sensory pathways inside the brain, credit reporting neurogenesis.

Patient, Graham Small, suffers from a paradoxical state called Sightless Sight. He is totally window blind, but , they can sense activity with both eye in his kept field of vision and never his correct. Dr . Ramachandran has decided that eye-sight is definitely not seeing and that blind view is the ability to find things, but is not to be aware of them. He found that there are two separate eye-sight pathways- a newer pathway which goes to the aesthetic cortex and an older pathway that is coupled to the brain stem. Every pathway observes different aspects of vision.

The visual bande is for consciously see some thing and the path connected to the brain stem is relative to reflexive tendencies. DR . Ramachandran says which the reason Graham doesn’t observe anything, yet can impression its existence due to harm in the image cortex.

In a case similar to Graham Small, Peggy Palmer suffers from visual neglect caused by a stroke in the parietal lobes of the brain. Dr . Ramachandran explains that parietal bougie create a three dimensional layout of the world around all of us, which allows all of us to find their way our course. The patient are able to see, but simply on one aspect or the different, i. at the. she simply sees half of what is really there.

During an try things out where the affected person was asked to draw a picture of your daisy coming from memory, the girl was only able to pull the right half of the daisy. Right up until, it was delivered to her interest, she acquired no idea that she was only pulling half of the picture. This gives us evidence there is not only a physical problem, yet a problem of consciousness. With 30 areas in the head for seeing, visual insight divides in to two parallel streams of processing. 1 called the How pathway, is concerned with navigation plus the other named the “What pathway is concerned with acknowledgement.

David Silvera has problems for the “What pathway and has been clinically determined to have Capgras Problem. The patient does not recognize familiar people and places. He contends that his mother and father are not who have they say they are and does not identify his own house. The patient sometimes refers to him self as he was not David. This individual does recognize his parent’s voices above the phone.

Doctor Ramachandran is convinced that the source of this condition lies in the eventual lobes. The amygdala builds visual emotion and if it’s getting a meaning from the eventual lobe when you look at an object, you can’t react to it psychologically. Therefore you refuse what you are seeing. Dr . Ramachandran has identified that a person’s intellectual look at of the world can be closely connected to emotional reactions to the universe and that Capgras Syndrome can heal alone over time. This is further evidence of neurogenesis.

Steve Sharon suffers from violent seizures caused by Temporal Lobe Epilepsy. These seizures have activated religious and extreme emotional feelings of connection to the earth. Patient frequently gets philosophical and says he has great, inexplicable feelings pertaining to objects no more than a grain of crushed stone after every single seizure.

Doctor Ramachandran is convinced it is possible that the seizure activity creates outrageous emotions that could be interpreted like a sense of God’s existence and that it includes something to do with the temporal lobe wiring which will helps to deal with the world emotionally. Basically, it helps you figure out how trivial something is and how crucial something is.

Your doctor feels that parts of the temporal lobe are conducive to faith based belief and that this condition opens up subjects of God and religion to get studied by scientists. This individual theorizes that repeated seizures are leading to a strengthening of the pathways so that every thing, no matter how small , has serious significance towards the patient.
