Des classes sociales aux classes cognitives

Dans ce texte, l’auteur poursuit deux objectifs. Première- ment, il tente de montrer que, désormais, les compétences cognitives priment la classe sociale lorsqu’il s’agit d’obtenir un emploi prestigieux. Pour ce faire, il examine cinq aspects : le statut social et les compétences cognitives, l’effet Flynn, l’interaction entre l’héritabilité et l’environne- mentalité, l’homogamie éducationnelle et la mondialisation. Deuxièmement, l’auteur présente quelques conséquences sociales de cet état de fait aux plans social et éducatif, dont l’idéologie méritocratique.

Behavioral neurosciences in Latin-American psychology journals

Behavioral neurosciences have evolved from other disciplines such as psychology, psychiatry and neurology, becoming a prominent area within general neuroscience. In mainstream psychology, neurosciences currently have an important role. In this paper we documented articles published in four Latin-American psychology journals and we classified these papers as empirical or theoretical. We analyzed the main topics covered in the behavioral neurosciences. Most of reported research used humans and rats as study subjects, although other species have also been used as models. Data suggest behavioral neurosciences currently play a growing and prominent role in Latin American psychology.

What the cognitive neurosciences mean to me

Cognitive Neuroscience is an interdisciplinary area of research that combines measurement of brain activity (mostly by means of neuroimaging) with a simultaneous performance of cognitive tasks by human subjects. These investigations have been successful in the task of connecting the sciences of the brain (Neurosciences) and the sciences of the mind (Cognitive Sciences). Advances on this kind of research provide a map of localization of cognitive functions in the human brain. Do these results help us to understand how mind relates to the brain? In my view, the results obtained by the Cognitive Neurosciences lead to new investigations in the domain of Molecular Neurobiology, aimed at discovering biophysical mechanisms that generate the activity measured by neuroimaging instruments. In this context, I argue that the understanding of how ionic/molecular processes support cognition and consciousness cannot be made by means of the standard reductionist explanations. Knowledge of ionic/molecular meclianisms can contribute to our understanding of the human mind as long as we assume an alternative form of explanation, based on psycho-physical similarities, together with an ontological view of mentality and spirituality as embedded in physical nature (and not outside nature, as frequently assumed in western culture).

Lo spazio senso-motorio come rappresentazione dei comportamenti intersoggettivi. Una nuova ipotesi sperimentale dalla filosofia alle neuroscienze

La ricerca ha preso le mosse da tre ipotesi fondamentali: 1) Esiste un legame tra processi cognitivi di basso ed alto livello; 2) Lo spazio senso-motorio è una percezione soggettiva; 3) Lo spazio senso-motorio varia in funzione delle diverse modalità di interazione sociale. La tesi sostiene che lo spazio senso-motorio si lascia modulare dalla semplice co-presenza di un altro agente umano e da interazioni cooperative e non cooperative. I capitoli I, II, III, hanno lo scopo di scomporre e spiegare il significato della prima, seconda e terza ipotesi; giungendo a formulare la tesi centrale che sarà poi dimostrata sperimentalmente nel capitolo IV. Il capitolo V introduce future linee di ricerca nell’ambito dell’etica proponendo una nuova ipotesi sul legame che potrebbe sussistere tra la percezione dello spazio durante l’interazione sociale e i giudizi morali. Il lavoro svolto chiama ad operare insieme diverse discipline che concorrono a formare le scienze cognitive: la storia della filosofia, la filosofia della mente contemporanea, la neuropsicologia sperimentale ed alcuni temi della psicologia sociale.

Real-time closed-loop electrophysiology: towards new frontiers in in vitro investigations in the neurosciences

Reflected at any level of organization of the central nervous system, most of the processes ranging from ion channels to neuronal networks occur in a closed loop, where the input to the system depends on its output. In contrast, most in vitro preparations and experimental protocols operate autonomously, and do not depend on the output of the studied system. Thanks to the progress in digital signal processing and real-time computing, it is now possible to artificially close the loop and investigate biophysical processes and mechanisms under increased realism. In this contribution, we review some of the most relevant examples of a new trend in in vitro electrophysiology, ranging from the use of dynamic-clamp to multi-electrode distributed feedback stimulation. We are convinced these represents the beginning of new frontiers for the in vitro investigation of the brain, promising to open the still existing borders between theoretical and experimental approaches while taking advantage of cutting edge technologies.
