Stable representation of a naturalistic movie emerges from episodic activity with gain variability

نویسندگان

چکیده

Abstract Visual cortical responses are known to be highly variable across trials within an experimental session. However, the long-term stability of visual is poorly understood. Here using chronic imaging V1 in mice we show that neural repeated natural movie clips unstable weeks. Individual neuronal consist sparse episodic activity which stable time but gain Further, find individual episode, instead neuron, serves as basic unit week-to-week fluctuation. To investigate how population encodes stimulus, extract a one-dimensional representation movie, unsupervised method. Most fluctuation perpendicular stimulus encoding direction, thus leaving largely unaffected. We propose precise with coordinated changes keys maintain V1.

Representation Emerges from Coupled Behavior

We present Starcat, an architecture for emergent fluid cognition. We describe the role knowledge representation plays in Starcat, and share insights about that representation which have been discovered in the process of our research. These insights are chiefly that 1) emergent behavior drives emergent representation (whereas in traditional systems representation drives behavior), and 2) that wh...

in the past couple of decades sociocultural theory of sla and its implications in efl contexts have attracted attentions of research circles worldwide and aroused some controversies. firth and wagner (1997) have questioned the principles of the cognitive view which gives importance to mental constructs in favor of sociocultural view which highlights social and contextual constructs. but if soci...

A Naturalistic Open Source Movie for Optical Flow Evaluation

Ground truth optical flow is difficult to measure in real scenes with natural motion. As a result, optical flow data sets are restricted in terms of size, complexity, and diversity, making optical flow algorithms difficult to train and test on realistic data. We introduce a new optical flow data set derived from the open source 3D animated short film Sintel. This data set has important features...

Predicting episodic memory formation for movie events

Episodic memories are long lasting and full of detail, yet imperfect and malleable. We quantitatively evaluated recollection of short audiovisual segments from movies as a proxy to real-life memory formation in 161 subjects at 15 minutes up to a year after encoding. Memories were reproducible within and across individuals, showed the typical decay with time elapsed between encoding and testing,...
