Neural sequences: deductive principles and rules.

A neural sequence is set not only by deterministic, but also by chaotic rules. The former are, mainly, recency effects, while the latter intervene in the early stage of the performance. Chaotic-like sequences can be recognized by the presence, within them, of greater variations.

Neural sequences: experimental evidence and deductive principles.

Comprehensive study of brain performances implies reference to sequences of repetitive functional elements (events). In this particular experimental field, these are sequences of psychomotor reactions and particularly verbal reactions with different modalities of stimuli and pre-established intervals before responding. The organization of these sequences or temporal cycles is based on different sets of stimuli and series of processes that are measured through parameters related to trials that activate the central mechanism of working memory.

Trials and training with 100 self-rated verbal reactions and a theory of sequences.

Sequences of verbal reactions, in particular 100 self-rated reactions, were investigated in 51 normal subjects and 61 patients with different neurological disorders. The non-linear course of the sequences is highlighted, and the factors influencing the occurrence of variations are studied. Inter-individual differences in the first interstimulus intervals (ISI alpha), and deviations between ISI alpha and subsequent interstimulus intervals, were systematically measured and the distribution of the results analyzed in histograms: a bimodal distribution was found.

Integrative and facilitatory processes in premotor pathology and their application in training.

The role of the neurologist in rehabilitation goes beyond diagnosing the patient's disease and related functional disorders. This task, like dynamic diagnosis or the longitudinal evaluation of disease course and of the effects of treatments administered, can be carried out through consultations. In reality, the neurologist's direct intervention is required and should be oriented in three complementary directions.
