Chromatographic Data in Statistical Analysis of BBB Permeability Indices

open access: yesMembranes, 2023
Blood–brain barrier (BBB) permeability is an essential phenomena when considering the treatment of neurological disorders as well as in the case of central nervous system (CNS) adverse effects caused by peripherally acting drugs.

STUDIES IN THE PHYSIOLOGY OF THE NERVOUS SYSTEM. XV.: IMMEDIATE REFLEX PHENOMENA RESULTANT UPON COMPOUND STIMULATION IN DECEREBRATE PREPARATIONS [PDF]

open access: yesQuarterly Journal of Experimental Physiology, 1914
The present paper itself is the summary of a large number of experiments, and it is not possible again to refer to all the points described in it. The following may, however, be noticed:—1. Where the two antagonistic stimuli are commenced synchronously, “algebraic summation” (Sherrington) of the two “pure” reflexes may occur in the compound reaction ...

Cellular excitability and the regulation of functional neuronal identity: from gene expression to neuromodulation [PDF]

open access: yes, 2006
The intrinsic properties of a neuron determine the translation of synaptic input to axonal output. It is this input– output relationship that is the heart of all nervous system activity.

STUDIES IN THE PHYSIOLOGY OF THE NERVOUS SYSTEM. XX.: RHYTHMIC MOVEMENTS AS IMMEDIATE REFLEX PHENOMENA OF COMPOUND STIMULATION [PROGRESSION CONDITIONED BY ANTAGONISTIC REFLEX STIMULI] [PDF]

open access: yesQuarterly Journal of Experimental Physiology, 1914
1. The results described in this paper have previously been published in a more condensed form. They are now given in greater detail, and shew that in the low spinal, high spinal, and decerebrate preparations there may be evoked a rhythmic phenomenon during a period in which two afferent nerves—which when stimulated separately give antagonistic ...

Micropatterned substrates for studying astrocytes in culture

open access: yesFrontiers in Neuroscience, 2009
Recent studies of the physiological roles of astrocytes have ignited renewed interest in the functional significance of these glial cells in the central nervous system.

Augmentation of Mind-body Therapy and Role of Deep Slow Breathing [PDF]

open access: yes, 2009
Mind-body therapies have been shown to be effective in clinical treatment of disorders such as high blood pressure and stress. Significant differences in the effectiveness of mind–body therapies have been shown and a common link among the therapies has ...

Visual Cortex Plasticity: A Complex Interplay of Genetic and Environmental Influences

open access: yesNeural Plasticity, 2012
The central nervous system architecture is highly dynamic and continuously modified by sensory experience through processes of neuronal plasticity. Plasticity is achieved by a complex interplay of environmental influences and physiological mechanisms ...

Studying multisensory processing and its role in the representation of space through pathological and physiological crossmodal extinction

open access: yesFrontiers in Psychology, 2011
The study of crossmodal extinction has brought a considerable contribution to our understanding of how the integration of stimuli perceived in multiple sensory modalities is used by the nervous system to build coherent representations of the space that ...

STUDIES IN THE PHYSIOLOGY OF THE NERVOUS SYSTEM. XXI.: RHYTHMIC MOVEMENTS AS SUCCESSIVE (OR TERMINAL) REFLEX PHENOMENA OF COMPOUND STIMULATION [PROGRESSION CONDITIONED BY ANTAGONISTIC REFLEX STIMULI] [PDF]

open access: yesQuarterly Journal of Experimental Physiology, 1914
1. In the experiments described in this paper the occurrence of rhythmic phenomena in successive phases of compound reactions is shewn. Rhythmic phenomena thus occur in the third phase of such a compound reaction— that is, in a phase in which the background reflex is continued after the withdrawal of the interrupting reflex.

Spectral convergence in tapping and physiological fluctuations: coupling and independence of 1/f noise in the central and autonomic nervous systems. [PDF]

open access: yes, 2014
When humans perform a response task or timing task repeatedly, fluctuations in measures of timing from one action to the next exhibit long-range correlations known as 1/f noise. The origins of 1/f noise in timing have been debated for over 20 years, with
