Prefrontal Cortex and Recognition
Professor Earl Miller describes research that shows objects are recognized using higher brain regions, specifically the prefrontal cortex.
Visual categories were thought to be largely represented in the visual cortex and the more posterior parts of the brain. What we found is that these visual categories, at least learned visual categories, categories the monkeys had to be trained to use, are explicitly represented in the prefrontal cortex and not in visual cortex. That was a surprise to me and a surprise to a number of people in the field because we thought it would be happening at a lower level than what we actually discovered. It's happening at the highest reaches of the brain, at least for categories that are brand new learned categories.

1191. Neurons for Recognition
Professor Earl Miller explains that neurons in the prefrontal cortex respond to recognize very specific categories of object such as 'dog' or 'cat'.
1195. Brain regions and Object Identification
Professor Earl Miller explains that the visual cortex, inferior temporal cortex, and prefrontal cortex perform distinct functions in object identification.

1193. Categorization in the Brain
Professor Earl Miller discusses the importance of the brain's ability to categorize objects.
1244. Temporal Lobe
The temporal lobes contain a large number of substructures, whose functions include perception, face recognition, object recognition, memory, language, and emotion.
1190. Neurons and Perception
Professor Earl Miller discusses the hypothesis that an entire network of neurons are required to perceptually identify a single object.
2099. Prefrontal Cortex
The prefrontal cortex is thought to play an important role in 'higher' brain functions. It is a critical part of the executive system, which refers to planning, reasoning, and judgment.
2155. Dorsolateral prefrontal cortex
Professor Philip Shaw outlines the main functions of the dorsolateral prefrontal cortex, which include planning, attention, and working memory.
2288. The Amygdala and PFC Process Stress and Anxiety
Doctor Daniel Pine explains that in rodents, humans, and other primates, the amygdala mediates the stress response. The prefrontal cortex (PFC) is also important.
2326. TMS Treatment for Depression
Doctor Abraham Zangen discusses how transcranial magnetic stimulation (TMS) can stimulate different areas of the brain and treat depression.
