Consciousness in this sense has been compared to the blind spot in the retina where it is not an adaption of the retina, but instead just a by-product of the way the retinal axons were wired. Several scholars including Pinker, Chomsky, Edelman, and Luria have indicated the importance of the emergence of human language as an important regulative mechanism of learning and memory in the context of the development of higher-order consciousness (see Neural correlates section above). Another idea suggested where consciousness originates from a cell that has nestled itself in a blood capillary in the brain where the blood flow determines whether or not one is conscious. States of consciousness
There are some brain states in which consciousness seems to be absent, including dreamless sleep or coma. There are also a variety of circumstances that can change the relationship between the mind and the world in less drastic ways, producing what are known as altered states of consciousness. Some altered states occur naturally; others can be produced by drugs or brain damage. Altered states can be accompanied by changes in thinking, disturbances in the sense of time, feelings of loss of control, changes in emotional expression, alternations in body image and changes in meaning or significance.The two most widely accepted altered states are sleep and dreaming. Although dream sleep and non-dream sleep appear very similar to an outside observer, each is associated with a distinct pattern of brain activity, metabolic activity, and eye movement; each is also associated with a distinct pattern of experience and cognition.
Ophiasis is a form of alopecia areata characterized by the loss of hair in the shape of a wave at the circumference of the head.It gets its name from Greek ὄφις ophis snake because of the apparent similarity to a snake-shape and the pattern of hair loss.The term "sisaipho" is used to characterize the inverse pattern. Sisaipho is, almost, the reverse spelling of ophiasis. It is also called "ophiasis inversus".This form of hair loss "...targets the bodys own hair follicles, resulting in hair loss..." and although the immune system could be attacking hair follicle melanocytes, dermal papilla cells, and keratinocytes,” the foundational cause of this disease is yet to be confirmed. Pattern of hair loss
This is one among many types of patterns of hair loss, “in which they have band-link hair loss across the occiput.” Hair loss can take the form of patches of hair being removed and there can also be spontaneous regrowth as well. Duration of hair loss
Ophiasis hair loss is one form in which the hair loss can further deteriorate and can extend “for more than a year.”
