Analysis of the structure and function of the prefrontal area suggests that it is centrally involved in the operation of higher-order associative relationships involving the subordination of one set of associat
Motor skill learning relies on the primary motor cortex (M1), but how dopaminergic inputs from the ventral tegmental area (VTA) affect M1 at the neuronal and network levels remains unclear. Here, the authors show that VTA dopaminergic signaling is essential for reorganization of M1 layer 2-3 ...

2009) and then fine-tuned on the small target dataset in deep learning (Tan et al. 2018). The wealth of knowledge learned from the source dataset is implicitly encoded in huge parameters, making it possible for the target task to achieve better performance with limited samples. For brain ...

Historically, primary sensory areas were thought to function as feature detectors. These areas create a representation of the external world that would be transmitted to higher cortical areas where this representation would be integrated with information related to past experience and behavioural state. ...
It is worth noting that the drivers of food intake can- not be wholly grasped without bearing in mind the contri- butions of the brain–gut axis – an interdependent system impacting brain function and eating behavior via biochemi- cal signaling between the endocrine and nervous system ...
Associative memories are stored in distributed networks extending across multiple brain regions. However, it is unclear to what extent sensory cortical areas are part of these networks. Using a paradigm for visual category learning in mice, we investigat
