Abstract/Results: RESULTS:
We developed several neural network models based on dendritic computation. Dendrites as independent computational units enable simulation of a wide variety of perceptual and cognitive phenomena. Computer simulations showed that new neural networks with dendrites are able to explain how neural activity is modulated by attention in primary visual cortex and in extra-striate cortex. Also it was shown how visual search is performed among moving targets and for targets that change locations due to the eye movements. The model of the interaction between dorsal and ventral visual streams enabled simulation of classical Gestalt principles of figure-ground organization (size, contrast, and convexity) along with newly discovered principles such as lower region and top-bottom polarity. The same model of figure-ground organization produced brain activation consistent with brain imaging studies and with electrophysiological recordings in the monkey brain. The model of temporal grouping is able to explain how we segregate figures from background based on temporal changes alone. This model does not require neural synchronization in order to sense temporal patterns. Furthermore, we developed a neural model of semantic memory which is able to simulate recent experimental findings about interaction between language understanding and perception and action. We performed several cognitive experiments which showed that perceptual and motor variables facilitate semantic processing in agreement with the model. Our project provided computational evidence for the importance of dendrites for information processing in the nervous system and for understanding visual perception and cognition.

Title:
A computational model of fMRI activity in the intraparietal sulcus that supports visual working memory
Publication year: 2011

Visitante: / http://www.ncbi.nlm.nih.gov/pubmed/21866425
Abstract/Results: ABSTRACT:
A computational model was developed to explain a pattern of results of fMRI activation in the intraparietal sulcus (IPS) supporting visual working memory for multiobject scenes. The model is based on the hypothesis that dendrites of excitatory neurons are major computational elements in the cortical circuit. Dendrites enable formation of a competitive queue that exhibits a gradient of activity values for nodes encoding different objects, and this pattern is stored in working memory. In the model, brain imaging data are interpreted as a consequence of blood flow arising from dendritic processing. Computer simulations showed that the model successfully simulates data showing the involvement of inferior IPS in object individuation and spatial grouping through representation of objects' locations in space, along with the involvement of superior IPS in object identification through representation of a set of objects' features. The model exhibits a capacity limit due to the limited dynamic range for nodes and the operation of lateral inhibition among them. The capacity limit is fixed in the inferior IPS regardless of the objects' complexity, due to the normalization of lateral inhibition, and variable in the superior IPS, due to the different encoding demands for simple and complex shapes. Systematic variation in the strength of self-excitation enables an understanding of the individual differences in working memory capacity. The model offers several testable predictions regarding the neural basis of visual working memory.

Abstract/Results: ABSTRACT:
When searching for a target in a visual scene filled with distractors, the mechanism of inhibition of return prevents revisiting previously attended locations. We proposed a new computational model for the inhibition of return, which is able to examine priority or saliency map in a manner consistent with psychophysical findings. The basic elements of the model are two neural integrators connected with two inhibitory interneurons. The integrators keep the saliency value of the currently attended location in the working memory. The inhibitory inter-neurons modulate a feedforward flow of information between the saliency map and the output map which points to the location of interest. Computer simulations showed that the model is able to read-out the saliency map when the objects are moving or when eye movements are present. Also, it is able to simultaneously select more then one location, even when they are non-contiguous. The model can be considered as a neural implementation of the episodic theory of attention.

Objective of the proposed project is to develop and test new neural networks for visual perception and cognition, which includes dendrites as independent computational units. It is expected that the neural model with dendrites will exhibit greater capacity for information processing and its output will show greater similarity with human behavior and experience compared to previous models.
METHOD:
We used computer simulations in order to test the properties of the proposed models. Results of computer simulations are compared with the results obtained in previous brain imaging and behavioral research on humans and/or neurophysiological studies on primates. Also, we tested several predictions derived from the models using cognitive experiments on humans where we measured the speed and accuracy of responses to simple perceptual and cognitive tasks.
RESULTS AND CONCLUSIONS:
Computer simulations showed that new neural networks with dendrites are able to explain how attention influences neural activity in the visual cortex, how visual search is performed, how cortical activity gives rise to figure-ground organization and perception of temporal structure. Furthermore, we developed a neural model of semantic memory which is able to simulate recent experimental findings about interaction between language understanding and perception and action. We performed several cognitive experiments which showed that perceptual and motor variables facilitate semantic processing in agreement with the model. Our project provided computational evidence for the importance of dendrites for information processing in the nervous system and for understanding visual perception and cognition.

Expectations about the temporal structure of the world result in the aAttentional blink and repetition blindness
Publication year: 2012
Institution(s):

Abstract/Results: ABSTRACT:
We consider how repetition blindness and the attentional blink might arise from prior assumptions about the occurrence of task-relevant states of the world. Repetition blindness and the attentional blink are behavioral deficits in the identification of items during rapid serial visual presentation at varying delays after identifying the first "target." Here we propose that both of these effects are explained by rational inference given prior expectations about the timing of task-relevant world transitions. While such expectations would be helpful in the natural world, they may result in unanticipated biases in laboratory settings. We show that a rational model using prior expectations of the timing of task-relevant information captures the basic repetition blindness and the attentional blink effects, and also the specific distributions of errors made during the attentional blink.

Controlling target brain regions by optimal selection of input nodes
Publication year: 2024

Abstract/Results: ABSTRACT:
The network control theory framework holds great potential to inform neurostimulation experiments aimed at inducing desired activity states in the brain. However, the current applicability of the framework is limited by inappropriate modeling of brain dynamics, and an overly ambitious focus on whole-brain activity control. In this work, we leverage recent progress in linear modeling of brain dynamics (effective connectivity) and we exploit the concept of target controllability to focus on the control of a single region or a small subnetwork of nodes. We discuss when control may be possible with a reasonably low energy cost and few stimulation loci, and give general predictions on where to stimulate depending on the subset of regions one wishes to control. Importantly, using the robustly asymmetric effective connectome instead of the symmetric structural connectome (as in previous research), we highlight the fundamentally different roles in- and out-hubs have in the control problem, and the relevance of inhibitory connections. The large degree of inter-individual variation in the effective connectome implies that the control problem is best formulated at the individual level, but we discuss to what extent group results may still prove useful.
