Song birds communicate by singing and learn their songs through imitation. Since their discovery in the monkey brain, it has been suggested that mirror neurons mediate the mimicking of behaviour in primates and perhaps also underlie empathy and language acquisition in humans. Prather et al. now show that mirror-like neurons also exist in birds and are involved in song learning.

These findings show that there is a remarkable resemblance between HVCx 'auditory-motor' neurons in birds and 'visual-motor' mirror neurons in the frontoparietal cortex in monkeys, which respond when a monkey performs an action or sees that same action being performed. It has been suggested that in humans mirror neurons might have a role in language acquisition, and the findings of Prather et al. provide the first evidence that learned communication, at least in birds, might indeed involve the activation of mirror-like neurons.

Google Graphic search

It seems like Google has activated his "dorsal stream" because from now on while performing a graphic search You not only get an answer to "what" (ventral stream) but also as to "where" (dorsal stream).
Is Google just mimicring human conscious vision by integrating Google maps or has it at last gained some kind of inner network consciousness ?
Could somebody please wake up a local terminator !

Between math and Biology

Sunday morning thee and cake spiced with some very interesting bio-mathematical or physicobiological philosophy...eat in small portions. if You are interested more topics here...

The first half second
Recent advances in the study of visual cognition and consciousness have dealt primarily with steady-state properties of visual processing, with little attention to its dynamic aspects. The First Half Second brings together for the first time the latest research on the dynamics of conscious and unconscious processing of visual information, examining the time-course of visual processes from the moment a stimulus is presented until it registers in a behavioral response or in consciousness a few hundred milliseconds later. The contributors analyze this "first half second" of visual processing -- known as its microgenesis -- from a variety of perspectives, including neuroscience, neuropsychology, psychophysics, psychology, and neural network modeling.The book first treats conceptual, methodological, and historical issues and provides an integrated review of findings from recent studies on the neural underpinnings of consciousness. The book then turns to neurophysiological correlates of dynamic processing in vision, highlighting the temporal dimension of functional distinctions; visual masking and what it can tell us about the operation of both normal and abnormal brains; the dynamics of attentional mechanisms from electrophysiological, behavioral, and modeling perspectives; and temporal characteristics of object and feature perception. Finally, drawing on the foundations laid in earlier chapters, the book elaborates further on the dynamic relation of conscious and unconscious processes in vision. The First Half Second fills the need for an interdisciplinary dialogue on the study of the dynamic aspects of visual processing and, with its rich empirical and theoretical findings, charts promising directions for future research.About the EditorsHaluk Ögmen is Professor in the Department of Electrical and Computer Engineering at the University of Houston, and a member of the University of Houston Center for Neuro-Engineering and Cognitive Science.Bruno G.
