Perceptual inference

NC Aggelopoulos - Neuroscience & Biobehavioral Reviews, 2015 - Elsevier
Perceptual inference refers to the ability to infer sensory stimuli from predictions that result
from internal neural representations built through prior experience. Methods of Bayesian …

The receptive fields of inferior temporal cortex neurons in natural scenes

ET Rolls, NC Aggelopoulos, F Zheng - Journal of Neuroscience, 2003 - Soc Neuroscience
Inferior temporal cortex neurons have generally been found to have large visual receptive
fields that typically include the fovea and extend throughout much of the visual field. However, …

Responses of neurones of the rat suprachiasmatic nucleus to retinal illumination under photopic and scotopic conditions

NC Aggelopoulos, H Meissl - The Journal of physiology, 2000 - Wiley Online Library
We have examined the responses of neurones in the suprachiasmatic nuclei (SCN) of the
rat to retinal illumination under photopic and scotopic conditions to identify the types of …

Neuronal selectivity, population sparseness, and ergodicity in the inferior temporal visual cortex

L Franco, ET Rolls, NC Aggelopoulos, JM Jerez - Biological cybernetics, 2007 - Springer
The sparseness of the encoding of stimuli by single neurons and by populations of neurons
is fundamental to understanding the efficiency and capacity of representations in the brain, …

Scene perception: inferior temporal cortex neurons encode the positions of different objects in the scene

NC Aggelopoulos, ET Rolls - European Journal of …, 2005 - Wiley Online Library
Inferior temporal cortex (IT) neurons have reduced receptive field sizes in complex natural
scenes. This facilitates the read‐out of information about individual objects from IT, but raises …

Object perception in natural scenes: encoding by inferior temporal cortex simultaneously recorded neurons

NC Aggelopoulos, L Franco… - Journal of …, 2005 - journals.physiology.org
The firing of inferior temporal cortex neurons is tuned to objects and faces, and in a complex
scene, their receptive fields are reduced to become similar to the size of an object being …

Information encoding in the inferior temporal visual cortex: contributions of the firing rates and the correlations between the firing of neurons

ET Rolls, NC Aggelopoulos, L Franco, A Treves - Biological Cybernetics, 2004 - Springer
The encoding of information by populations of neurons in the macaque inferior temporal
cortex was analyzed using quantitative information-theoretic approaches. It was shown that …

An information theoretic approach to the contributions of the firing rates and the correlations between the firing of neurons

…, L Franco, NC Aggelopoulos… - Journal of …, 2003 - journals.physiology.org
To analyze the extent to which populations of neurons encode information in the numbers of
spikes each neuron emits or in the relative time of firing of the different neurons that might …

[PDF][PDF] Characterization of a descending system that enables crossed group II inhibitory reflex pathways in the cat spinal cord

NC Aggelopoulos, MJ Burton, RW Clarke… - The Journal of …, 1996 - Soc Neuroscience
In the cat, stimulation of group II afferents from hindlimb muscles evokes different crossed
reflex actions depending on the integrity of the spinal cord: with the cord intact, extensor …

The use of decoding to analyze the contribution to the information of the correlations between the firing of simultaneously recorded neurons

L Franco, ET Rolls, NC Aggelopoulos… - Experimental Brain …, 2004 - Springer
A new decoding method is described that enables the information that is encoded by
simultaneously recorded neurons to be measured. The algorithm measures the information that is …
