Sensory encoding
Web1 Jul 2024 · To address whether individual differences in sensory encoding affect response bias, I first computed the parameters d′ and c, which assume that the Gaussian distributions of evidence for the two stimulus categories have equal variance. To do so, I calculated the hit rate (HR) and false-alarm rate (FAR) by treating the letter X in Task 1, the blue color in … WebEncoding is the process of transforming sensory data into a format that can be remembered. Information is arranged and classified in this process to create useful patterns. Working memory, also known as short-term memory, is a temporary memory space that stores data for a small amount of time, usually a few seconds.

Web12 Sep 2024 · Different sensory encoding schemes have been tested in patients showing distinct effects and outcomes according to their impact on the neural activation. Here, I reported the most adopted neural stimulation strategies to artificially encode somatosensation into the peripheral nervous system. The real-time implementation of … Web9 Mar 2024 · When it comes to psychology, the term “encoding” describes how information enters our memory system from sensory input. This crucial first step in creating a new …
Web1 Oct 2014 · Abstract. The efficient coding hypothesis posits that sensory systems maximize information transmitted to the brain about the environment. We develop a precise and testable form of this hypothesis in the context of encoding a sensory variable with a population of noisy neurons, each characterized by a tuning curve. We parameterize the … Web27 Sep 2024 · However, many questions remain about the specific conditions under which the hippocampus may exert a direct influence on stimulus encoding and plasticity in V1. In this issue of Current Biology, Finnie et al. 12 tackle these questions and shed light on the precise involvement of the hippocampus in encoding sensory experiences within mouse V1.
Web7 Nov 2024 · The sensory measurement is defined as the latent value that represents the measured sensory input, which is affected by the repulsive bias in encoding but has not yet been affected by the attractive bias in decoding. Web15 Nov 2024 · We further established that acceleration of neural dynamics during sensory encoding and decision formation was directly linked to multisensory integration. Our results were consistent across both signal detection and categorization tasks. Taken together, the results revealed a continuous dynamic interplay between multisensory integration and ...
A sequence, or 'train', of spikes may contain information based on different coding schemes. In some neurons the strength with which an postsynaptic partner responds may depend solely on the 'firing rate', the average number of spikes per unit time (a 'rate code'). At the other end, a complex 'temporal code' is based on the precise timing of single spikes. They may be locked to an externa…
