  1. Ken Mogi, The Source of Variability in Neural Responses From MT.
    We analyzed the variability of response in records obtained from MT (V5) of awake, behaving monkeys and kindly provided to us by Newsome and Bair (see Newsome et al 1990 for Methods). Some sets of random dot kinematograms had been generated with a constant randomization seed (novar stimuli), while others had been generated with varying randomization seeds (var stimuli). The neural responses to novar stimuli exhibited a remarkable degree of consistent temporal modulation, while the responses to var stimuli were homogeneous (...)

    The privileged position of neural activity in biological neuroscience might be justified on the grounds of the nonlinear and all-or-none character of neural firing. To justify the neuron doctrine in cognitive neuroscience and make it both plausible and radical, we must consider the supervenience of elementary mental properties such as qualia on neural activity.

  3. Ken Mogi, Creativity and the Neural Basis of Qualia.
    In what computational aspect is the brain different from the computer? In what objective measures can the brain said to be “creative”? These are the fundamental questions that concerns the neural basis of human mental activity. Here we discuss several important aspects of the essential computational ingredients of human mind in order to understand the “creative” process going on in the brain. One of the key concepts is the nature of the source of "externality" that adds new ingredients to the (...) argue that in addition to information input and stochasticity, we need to consider a third possibility, namely "dynamics-embedded externality". We discuss how the neural origin of the subjective sensory qualities (qualia) is related to this aspect of creativity. The invariance of qualia under a certain class of transformation, and the mapping of discrete,. (shrink)

    _The concept of qualia describes the unique properties that_ _accompany our senses. It is an essential concept when we try to_ _understand the principle that bridges the neural firings in our_ _brain and our perception. The idea of qualia is also of crucial_ _importance when we try to study the functions of the brain from_ _an objective point of view. Qualia must be part of the_ _mathematical formulation of information we use to understand_ _the function of the (...)
