A Vision of the Brain The Laboratory of Neurobiology headed by prof. Semir Zeki is offering the book A Vision of the Brain for free download. As the book is out of print and the author is not going to edit a second edition, they are offering it freely worldwide. To get the PDF, you just have to register in their website. A Vision of the Brain is one of the most important books, published in 1993, about how brain works to decode the reality, targeted at non-neuroscientists.

Autism and Neuropsychology, by Marisa Marzillo Autism is a lifelong disorder that has become the discussion of many media outlets; it is a disorder that causes abnormal neurological development. It seems that lately autism prevalence is increasing, which is causing a demand for professionals to investigate on what causes autism. Autism disorder is characterized by different behavior including social impairments, difficulty in communication, and restrictive patterns of behavior. Individuals living with autism don’t have a lower IQ than most people, but it is common that they have weak social interaction. Researchers have stated that it is unclear what causes autism; it ranges from environmental surroundings to a strain on normal brain development.

Amygdala Figure 1: Location of amygdala in the brain (reproduced from Wikipedia under GFDL). The amygdaloid region of the brain (i.e. the amygdala) is a complex structure involved in a wide range of normal behavioral functions and psychiatric conditions. Not so long ago it was an obscure region of the brain that attracted relatively little scientific interest. Nature Raphael Lis, Charles C. Karrasch, Michael G. Poulos, Balvir Kunar, David Redmond, Jose G. Barcia Duran, Chaitanya R. Visual problems have a role in dyslexia ScienceWise - Jan/Feb 2009 Dr Kristen Pammer Within the visual cortex there are two distinct processing pathways. The mangocellular pathway deals with conceptualising the movement of objects and their position in space. The pavocellular or ventral pathway is concerned with detailed visual information used for the recognition of objects.

Chapter 12: Attention and Consciousness Attention involves top-down (voluntary) goal-directed processes and bottom-up (reflexive), stimulus-driven mechanisms. They influence the way information is processed in the brain and can occur early during sensory processing. Balint's syndrome is a visual attention and awareness deficit. Someone who has this syndrome can only perceive one object at a time. the hormone of love "The hormone best known for its role in inducing labor may influence our ability to bond with others, according to researchers at the University of California, San Francisco. In a preliminary study, the hormone oxytocin was shown to be associated with the ability to maintain healthy interpersonal relationships and healthy psychological boundaries with other people. The study appears in the July issue of Psychiatry. "This is one of the first looks into the biological basis for human attachment and bonding," said Rebecca Turner, PhD, UCSF adjunct assistant professor of psychiatry and lead author of the study.

Neuroscience Neuroscience is the scientific study of the nervous system.[1] Traditionally, neuroscience has been seen as a branch of biology. However, it is currently an interdisciplinary science that collaborates with other fields such as chemistry, computer science, engineering, linguistics, mathematics, medicine and allied disciplines, philosophy, physics, and psychology. It also exerts influence on other fields, such as neuroeducation[2] and neurolaw. The term neurobiology is usually used interchangeably with the term neuroscience, although the former refers specifically to the biology of the nervous system, whereas the latter refers to the entire science of the nervous system. Because of the increasing number of scientists who study the nervous system, several prominent neuroscience organizations have been formed to provide a forum to all neuroscientists and educators.

Around half of the boutons in the main thalamorecipient L4 carried orientation-tuned information, and their orientation and direction biases were also dominant in the L4 neuron population, suggesting that these neurons may inherit their selectivity from tuned thalamic inputs. Cortical neurons in all layers exhibited sharper tuning than thalamic boutons and a greater diversity of preferred orientations. by weihler Aug 11
