On the existence of a purely abstract cognitive system in the brain that is based on single cells
by Asim Roy Feb. 28, 2017

Feb. 28, 2017

The following paper was published recently in Frontiers in Psychology, Cognition: “The theory of localist representation and of a purely abstract cognitive system: The evidence from cortical columns, category cells and multisensory neurons” http://journal.frontiersin.org/article/10.3389/fpsyg.2017.00186/full On the extensive use of abstract multisensory neurons in the brain There is now substantial neurophysiological evidence for a purely abstract cognitive system in the brain that is based on single cells. The evidence primarily comes from abstract category cells and multisensory neurons. Multisensory neurons provide a remarkable insight to the brain. Ghazanfar & Schroeder (2006) claim that multisensory integration extend into early sensory processing areas of the brain and that neocortex is essentially multisensory. Saleem, Ayaz, Jeffery, Harris & Carandini, M. (2013) report finding nearly half of V1 neurons in mice to be multimodal integrating visual motion and locomotion during navigation. And Klemen & Chambers (2012) notes that there is now “broad consensus that most, if not all, higher, as well as lower level neural processes are in some form multisensory.” So abstractions are used extensively in the brain. And these abstraction are layered, sometimes integrating information from two modalities, sometimes three and so on. Much more evidence is discussed in the paper. On the absence of evidence for distributed representation It is also argued in the paper that there is no evidence for distributed representation in the brain, since, as per McClelland, the dense form (not the sparse form) is the only form that counts. And there is absolutely no evidence for the dense form (Panzeri et al. 2015). On the compatibility of grounded cognition and an abstract cognitive system It is also argued in the paper that such an abstract cognitive system is fully compatible with grounded and embodied cognition. And Barsalou’s (2008, p. 618) statement is very consistent with the claims made in this paper: “From the perspective of grounded cognition, it is unlikely that the brain contains amodal symbols; if it does, they work together with modal representations to create cognition.” One of Barsalou’s questions was (p. 631): “Can empirical evidence be found for the amodal symbols still believed by many to lie at the heart of cognition?” I think there is extensive evidence now that there indeed are amodal symbols in the brain and in the brains of many species. The discovery of this purely abstract cognitive system in the brain has the potential to resolve deep theoretical conflicts in cognitive science that’s almost four decades old.

Funded PhD studentship in computational cognitive neuroscience
by Srivas Chennu Feb. 24, 2017

Feb. 24, 2017

Applications are invited for a funded PhD studentship with Dr Srivas Chennu in the School of Computing at the University of Kent (UK) to be based in our Medway Campus, to begin in September 2017 or shortly thereafter. The PhD project will focus on the research topics below, spanning computational and translational neuroscience. ==Neurodynamics of consciousness== Understanding how neural dynamics generate human consciousness is a grand challenge for neuroscience. We develop computational frameworks that use neuroscientific data (EEG/MEG/fMRI) to study the brain network correlates of consciousness during normal wakefulness, and in altered states like sleep, sedation and meditation. We also apply this science to build computational tools for improving diagnostics and prognostics during emergence from coma, and in prolonged disorders of consciousness (including the so-called vegetative and minimally conscious states). These tools could eventually be deployed right at the patients' bedside to visualise, quantify and track how their brains are recovering after injury. ==Deep neural network models of cognition== The idea that the brain is a hierarchical neural network designed for predictive cognition is persuasive one. In this view, the cortex implements Bayesian inference to maintain a successively complex hierarchy of predictive models of sensory causation. Alongside, deep learning can enable us to build dense neural networks based on complex neuroimaging datasets. We combine EEG/MEG with these modelling frameworks to describe how recurrent neural information processing realises predictive cognition in the brain. The successful applicant will be able to capitalise on Dr. Chennu’s strong research links with empirical and clinical collaborators at the Universities of Cambridge, Birmingham, Liége (Belgium), and Western Ontario (Canada). They will be embedded within the Data Science research group within the school, which brings together academics with expertise in signal processing, brain-computer interfacing, machine learning and computational intelligence. More information is available is available at Dr Chennu’s academic website: www.cs.kent.ac.uk/people/staff/sc785/ ==The School of Computing, University of Kent== The School of Computing has a reputation for high-quality research, with over 40 current PhD students. Our research activity is wide ranging and takes place within focused Research Groups which provide a vibrant research community for all members, staff or student. The School of Computing was ranked highly in the recent government run Research Excellence Framework (REF) exercise. Our research intensity was ranked 12th out of 89, with superb impact – 100% of our research impact ranked world leading or internationally excellent. The University of Kent is a leading university with a commitment to excellence in teaching and research.
