“…The cellular ground of association between brain physiology and psychology is the function of PyrNs. This means that PyrNs provide an opportunity for the basis of sensory processes (including visual, auditory, gustatory, olfactory, and cutaneous systems) to participate in the higher cognitive functions (such as emotion, learning, and memory) [92,93]. Indeed, populations of PyrNs were observed in low-level sensory cortices, including primary somatosensory, visual, and auditory cortex, with PyrNs located in high-level areas such as the prefrontal cortex (PFC).…”

The mechanism of brain information processing unfolds within spatial and temporal domains inherently linked to the concept of space–time symmetry. Biological evolution, beginning with the prevalent molecular chirality, results in the handedness of human cognitive and psychological functions (the phenomena known as biochirality). The key element in the chain of chirality transfer from the downstream to upstream processes is the pyramidal neuron (PyrN) morphology–function paradigm (archetype). The most apparent landmark of PyrNs is the geometry of the cell soma. However, “why/how PyrN’s soma gains the shape of quasi-tetrahedral symmetry” has never been explicitly articulated. Resolving the above inquiry is only possible based on the broad-view assumption that encoding 3D space requires specific 3D geometry of the neuronal detector and corresponding network. Accordingly, our hypothesis states that if the primary function of PyrNs, at the organism level, is sensory space symmetry perception, then the pyramidal shape of soma is the best evolutionary-selected geometry to support sensory-motor coupling. The biological system’s non-equilibrium (NE) state is fundamentally linked to an asymmetric, non-racemic, steady state of molecular constituents. The chiral theory of pyramidal soma shape conceptually agrees that living systems have evolved as non-equilibrium systems that exchange energy with the environment. The molecular mechanism involved in developing PyrN’s soma is studied in detail. However, the crucial missing element—the reference to the fundamental link between molecular chirality and the function of spatial navigation—is the main obstacle to resolving the question in demand: why did PyrNs’ soma gain the shape of quasi-tetrahedral symmetry?

This paper revisits global kinematical performance indexes within the scope of manually teleoperated serial robots in accounting for the human operator. The proposed theory is grounded on the knowledge of a human-centered coordinate system to parameterize the task space. Perceptual parameters are also introduced in the Man-system interaction effort. The resulting expression is used to derive a local kinematical index and a probability density. The global index is computed by integration over the whole robot's jointspace. The proposed index is proved to be relevant by outperforming classical indexes in predicting the end-user satisfaction of medical tele-sonography robots. Therefore this index could be considered as a criterion design to optimize the kinematics of homogenous non-redundant serial telerobots.
