چکیده
Mind: " By convention colour, by convention cold, by convention bitter: in reality atoms and void. " Senses: " Poor mind, do you take your evidence from us and then try to overthrow us? Our overthrow is your fall. " Democritus (460-370 BC)

Heterogeneous response dynamics in retinal ganglion cells: the interplay of predictive coding and adaptation.
To make efficient use of their limited signaling capacity, sensory systems often use predictive coding. Predictive coding works by exploiting the statistical regularities of the environment--specifically, by filtering the sensory input to remove its predictable elements, thus enabling the neural signal to focus on what cannot be guessed. To do this, the neural filters must remove the environmen...

متن کاملThe statistics of the vestibular input experienced during natural self-motion differ between rodents and primates.
KEY POINTS In order to understand how the brain's coding strategies are adapted to the statistics of the sensory stimuli experienced during everyday life, the use of animal models is essential. Mice and non-human primates have become common models for furthering our knowledge of the neuronal coding of natural stimuli, but differences in their natural environments and behavioural repertoire may ...
متن کاملTesting the Efficiency of Sensory Coding with Optimal Stimulus Ensembles
According to Barlow's seminal "efficient coding hypothesis," the coding strategy of sensory neurons should be matched to the statistics of stimuli that occur in an animal's natural habitat. Using an automatic search technique, we here test this hypothesis and identify stimulus ensembles that sensory neurons are optimized for. Focusing on grasshopper auditory receptor neurons, we find that their...
متن کاملScale-Invariant Adaptation in Response to Second-Order Electro-Sensory Stimuli in Weakly Electric Fish
Background: Natural stimuli can range orders of magnitude, and their encoding by the brain remains a central issue in neuroscience. An efficient way of encoding a natural stimulus is by changing a neuron’s coding rule in tandem with changes in the stimulus. This phenomenon is called sensory adaptation. However, sensory adaptation creates ambiguity in the neural code, as different stimuli can pr...
