Neuroanatomy of memory.

P38: Neuroanatomy of Post Traumatic Stress Disorder

Posttraumatic stress disorder (PTSD) is a disorder of emotional and mental stress occurring as an outcome of injury or severe emotional shock. Several Neuroimaging studies in humans have shown the functions and relationship between the anatomical changes of brain and PTSD. The three major areas of the brain are affected by PTSD .These three areas are the amygdala, hippocampus and prefrontal cor...

The cognitive neuroscience of human memory since H.M.

Work with patient H.M., beginning in the 1950s, established key principles about the organization of memory that inspired decades of experimental work. Since H.M., the study of human memory and its disorders has continued to yield new insights and to improve understanding of the structure and organization of memory. Here we review this work with emphasis on the neuroanatomy of medial temporal l...

Neuroanatomy of verbal working memory as a diagnostic biomarker for depression.

The functional neuroanatomy of verbal working memory is a potential diagnostic biomarker for depression. Twenty patients with unipolar depression and 20 healthy controls performed a variable load version (n-back) of the task. Functional MRI data were analysed with support vector machine methods. Diagnostic classification was highest at the mid-level of task difficulty (2-back) (sensitivity 65%,...

Neuroanatomy: Mushrooming mushroom bodies

A revolution is spreading in the study of mushroom bodies, structures within the insect brain that mediate learning and memory processes and pheromonal discrimination of the opposite sex.

Functional neuroanatomy of the medial temporal lobe memory system.

A novel approach to an old problem: analysis of systematic errors in two models of recognition memory.

For more than a decade, the high threshold dual process (HTDP) model has served as a guide for studying the functional neuroanatomy of recognition memory. The HTDP model's utility has been that it provides quantitative estimates of recollection and familiarity, two processes thought to support recognition ability. Important support for the model has been the observation that it fits experimenta...
