Occipital+Lobe

 The occipital lobe contains the primary visual cortex and is the main visual processing center of💩💩💩💩💩💩💩💩💩💩💩💩💩💩 🌟the brain. Also it is very good for pooping healthy poos. [] There are no individual structures in the occipital lobe.

**Current Research/ Experiments**

[|Brain Training May Help Blindsighted See] Brain-training may help patients who suffer from blindness due to injury in the occipital lobe gain some vision. The patients’ brain processes some visual actions and must be retrained to gain awareness of their surroundings. If the brain is able to be trained to see again then it oopopoop🐮🐘🐒🐗🐮🐵🐍🐥🐮🐒🐥🐮🐔🐣🐽chocolated be trained to do a number of other things that patients’ have lost due to a variety of different circumstances. This research could open a whole new realm of psychology. It also gives others hope that in future cases of brain injury a solution may be possible.

[|Prenatal Alcohol Exposure Damages White Matter, The Brain's Connective Network] Alcohol may effect the white matter in the prenatal brain. Alcohol consumption could alter the integrity of the developing matter. Effected white matter in the occipital lobe could relate to “altered visual-spatial abilities in individuals with fetal alcohol spectrum disorders.” This is important to those psychologists studying children’s progression and advancement. It also shows mothers more negative effects of drinking alcohol while pregnant. [|How BrainPort Works] The BrainPort is a new device that scientists say can help blindsighted people see.The technology manipulates the brain’s sensory output by using the tongue.The tongue sends visual output in the same way that the eyes receive visual input and the data is sent to the brain to process and form images.This technology can help other psychologists start to believe that it is possible to invent technology that can allow other senses to be regained.The first step though is to study the relationship between the other senses to see if any have similar characteristics like the tongue and eyes.This gives many people hope for sight again and possibly other things such as hearing.


 * Medical Case Studies**

[|Alexia without agraphia: a study of a case of verbal alexia without accompanying colour-naming defect (2004)] This case involves a 47 year old man who developed a reading problem after experiencing a hemorrhagic lesion in the left region of the occipital lobe. The man’s difficultly in reading, however, was not followed with problems in writing. There are many variations of alexia; each with its own symptoms and contrasting drawbacks. The man’s symptoms prompt researchers to believe that alexia is contained in the left hemisphere of the brain where most cases of patients have had damage. [|Dream loss in stroke patient linked to occipital lobe damage]  A 73 year old woman experienced a bilateral occipital artery obstruction and then reported dream loss. The patient was diagnosed with Charcot-Wilbrand syndrome but her sleep structure was mostly normal. Doctors hypothesized that there was damage done to the inferior lingual gyrus of the occipital lobe which has a great deal to do with dreaming and vision. Damage to this ridge of the lobe is what is thought to have had a hand in CWS arising for the otherwise healthy woman. [|Occipital lobe epilepsy in adults] In this case study, 536 patients were examined and 22 were diagnosed with occipital lobe epilepsy. The case explains that the patients were monitored for an average of 3 years and it was found that when patients were not experiencing the effectiveness of the antiepileptic medication, “symptoms of loss” were noticed. These included scotomas and amaurosis, which are blind spots in the visual field and loss of sight, respectively. Researchers also found that lesions in the lobe occurred 1 out of every 3 patients and were most likely the main cause of the epilepsy.

**The Occipital Lobe song –To the Tune of I Can See Clearly Now**  I can see clearly now, my visions good My occipital lobe is doing its job I can see everything in front of me It’s gonna be a bright, bright Sun-Shiny day It’s gonna be a bright, bright Sun-Shiny day

I can’t see clearly now I got a lesion Which means I can have hallucinations Gone are the days I could see clearly It’s gonna be a gloom, gloom Gloom gloomy day It’s gonna be a gloom, gloom Gloom gloomy day

Oh yes I can see it now, sort of The lesions left me with color blindness Here is the rainbow I’ve been prayin’ for To bad I can’t see, see I can’t see The bright colors
