Activities of visual cortical and hippocampal neurons co-fluctuate in freely moving rats during spatial behavior
Visual cues exert a powerful control over hippocampal place cell activities that encode external spaces. The functional interaction of visual cortical neurons and hippocampal place cells during spatial navigation behavior has yet to be elucidated. Here we show that, like hippocampal place cells, many neurons in the primary visual cortex (V1) of freely moving rats selectively fire at specific lo...
متن کاملBrane necklaces and brane coils
We investigate D-term strings in angled inflation and show how they could be distinguished from conventional cosmic strings. In angled inflation, D-term strings are Dp−2 branes that are extended between Dp branes. The Dp−2 brane has a flat direction in compactified space, along which the endpoint of the Dp−2 brane can move freely on the Dp brane. Then naturally the position of the Dp−2 brane co...
متن کاملNeural Networks in Which Synaptic Patterns Fluctuate with Time
We study a stochastic neural-network model in which neurons and synapses change with a priori probability p and 1& p, respectively, in the limit p 0. This implies neuron activity competing with fast fluctuations of the synaptic connections in fact, random oscillations around values given by a learning (for example, Hebb's) rule. The consequences for the system performance of a dynamics constant...
متن کاملChemokines fluctuate in the progression of primary breast cancer.
BACKGROUND Many studies have demonstrated that chemokines and their receptors play important roles in breast cancer. However, few of them focus on the concentration change of chemokines along breast cancer evolvement, especially for primary breast cancer. PURPOSE OF THE STUDY To investigate the effects of chemokines and their receptors on different stage of primary breast cancer, and to find ...
متن کاملWhy Does Inventory Investment Fluctuate So Much During Contractions
Inventory investment appears to have a significant impact on the movement of aggregate output during business cycle contractions. Recent empirical evidence has raised doubts about the often used assumption of a bufferstock/production-smoothing motivation for inventory. Work by Blinder and Maccini suggests that the use of an (S,s), or intermittent adjustment decision rule, better explains the st...
