Scientists are not sure how the brain follows the tracks of time. One theory holds that it has a group of cells specialized to record the intervals (间隔)of time while another theory holds that some neural processes(神经突)act as an inside clock. Whichever theory it may be studies find ...
and number of neural connections in the amygdala, 和大脑恐惧中心——杏仁体 your brain's fear center. 的神经连接数量。 And as levels of cortisol rise, 随着皮质醇水平的上升, electric signals in your hippocampus, 你海马体里面的电信号 the part of the brain associated with learning, memories, and...
Deep learning architectures have many variants and some have recurrent connections in addition to feedforward connections, yet they predominantly share the structure of a deep hierarchy. The layered, hierarchical structure that today’s deep learning architectures commonly adopt was inspired by earlier ...
Where processing in the SpaN model is defined by a neural network which models the spatial representation and comparison of numerical information in the brain. There are three key features that put the model into its own unique niche in the field. First, it describes the dynamics of the mechan...

Shepherd's enthusiasm in exploring this meeting of neural science and sensory input is infectious. He provides readers with a novel perspective that will enhance their appreciation of the pleasures of tasting fine wines, and inspire scientists and laypersons alike to test his hypotheses and extend ...
The human nervous system ©HowStuffWorks.com Every animal you can think of -- mammals, birds, reptiles, fish, amphibians -- has a brain. But the human brain is unique. Although it's not the largest, it gives us the power to speak, imagine and problem solve. It is truly an amazing...
"This new detailed view of brain organization at thesingle-celland functional levels had not been described before," Samee said. "Theneural network modelapproach we have developed in this work presents an 'instruction manual' for other researchers to use to study other areas of thebrainor other...
NIH scientists discovered that intense neural conversations thought to underlie learning and memory may be fueled by an energy-sensing feedback loop. Here scientist monitored energy levels in the form of ATP as neurons talked to each other. Credit: Sheng lab NINDS/NIH. Our thoughts, feelings, an...
"How the brain is organized to help make decisions is a big, fundamental question, and theneural circuitry—how neurons are connected to one another—in brain areas that are important for decision-making isn't well understood," said Wei-Chung Allen Lee, associate professor of neurobiology in t...
