Chasing the Trace
Event memories are stored in hippocampal-cortical networks. In this issue of Neuron, two studies, Cowansage et al. (2014) and Tanaka et al. (2014), tag active cells during memory encoding and optogenetically manipulate the activity of these "engram" cells during subsequent recall to reveal how hippocampal and cortical cell ensembles interact during retrieval.
متن کاملChasing the cell assembly.
Although we know enormous amounts of detailed information about the neurons that make up the cortex, placing this information back into the context of the behaving animal is a serious challenge. The functional cell assembly hypothesis first described by Hebb (The Organization of Behavior; a Neuropsychological Theory. New York: Wiley; 1949) aimed to provide a mechanistic explanation of how group...
متن کاملChasing the BSE agent
The UK and its anxious neighbours are currently focusing on foot and mouth disease but agricultural researchers are still working on a much deeper and worrying problem: BSE and its human form, new variant CJD. Unlike foot and mouth disease, much remains unknown about the aberrant prion protein agent of BSE and how it causes disease. One of the biggest stumbling blocks to research is the lack of...
متن کاملChasing Constrained
We investigate the implication problem for constrained tuple-generating dependencies (CTGDs), the extension of tuple-and equality-generating dependencies that permits expression of semantic relations (constraints) on variables. The implication problem is central to identifying redundant integrity constraints, checking integrity constraints on constraint databases, detecting the independence of ...
متن کاملChasing chaos
Both simple and hybrid genetic algorithms encounter difficulties when presented with a function which has multiple values. Similarly, changing environments or functions which change rapidly present other problems. This paper presents an algorithm that is capable of coping with both of these scenarios: it can accommodate multiple solutions simultaneously and can track changes in optima efficient...
