10. 2011 : Workshop on song learning

Arthur LEBLOIS — 2011-11-09T16:07:53Z

International workshop : Physiological mechanisms of song learning and production


Program of the workshop


Poster

Songbirds use learned vocalizations to communicate and display a network of nuclei dedicated to song learning and production. Vocal learning in songbirds as in humans involves three behavioral phases (possibly overlapping) likely reflecting distinct neural processes : (i) sensory learning, during which the young bird memorize the song(s) of one or more adult tutor(s) ; (ii) sensory-motor learning, with the production and slow perfection of an initially unstructured song ; and finally (iii) stereotypic production of the crystallized song after learning is completed. The specific involvement and role of the various brain circuits to the underlying neuronal processes remain only partly understood.

The workshop will present new advances in research areas aiming at uncovering the neural mechanisms involved in vocal learning in songbirds, from cellular physiology and genetics to behavior. It will be divided into three sessions reflecting the three phases of vocal learning : (i) sensory learning : representation and memorization of the song template(s) (ii) motor learning : genes, synapses and neurons involved in the modification of the vocal output (iii) vocal production : complexity of the song control system, from spikes to notes.

2011 : Symposium on Working Memory and Decision Making

Hervé Suaudeau — 2011-03-01T16:58:18Z


PDF version of program

Working Memory (WM) refers to structure and processes that support temporary storage and processing of information for behavioral purposes. It has been implicated as a critical contributor to essential cognitive functions such as reasoning, planning and learning. The best investigated neuronal correlate of WM is the so-called persistent activity found in several cortical areas during delayed-response tasks, that is enhanced/suppressed spiking activity initiated by stimulation and maintained along the delay period. Still today however, 50 years since the term was first used in behavioral sciences, WM functional architecture and its underlying physiological machinery alike remain elusive. Do WM functions result from the operations of one specialized system or from the coordinated recruitment of non- dedicated brain systems ? In either scenario, what is the function persistent activity is serving ? What are the physiological mechanisms that generate persistent activity ?

Investigation of WM and its neuronal correlates has been using the delayed-response paradigm and a correlative stimulus-neural activity-response approach as the chief experimental tools. Temporary memory storage is, however, only one of the potential demands likely to be made upon WM. Its prime function is rather the coordination of computational resources to produce behavior, that is, decision-making. We are convinced that focusing more on the 'working' part of the term 'Working Memory' will provide important breakthroughs in answering fundamental, still-unanswered questions about WM computational and mechanistic functioning.

Theoretical and modeling studies have investigated in the last years the possible network and cellular mechanisms which could underlie the initiation, maintenance, selectivity and extinction of persistent activity, learning and conversion of delay activity into motor responses, and the relationship between persistent activity and decision making. The goal of this symposium is to confront these theories and models with the most recent experimental data from electrophysiological, imaging and psychophysics experiments.

Physiology of the cerebellum :development, synaptic transmission and plasticity

The cerebellum contains half of the neurons of the brain, but little is truly understood of its role. Traditionally, the cerebellum has been considered a structure devoted to motor control (motor coordination, reflexes adaptation, motor learning...). In reality though, its contribution to motricity is only the most studied aspect of cerebellar functions. Recent studies performed on Humans, show that the cerebellum contributes significantly to cognitive functions (such as attention and language) and emotion.

I believe that the future development of functional imaging techniques and in vivo recording procedures will reveal that this « little brain » plays key and unexpected roles in brain function.

In the meantime, the cerebellum remains an incredible model for understanding neuronal communication and the computational capabilities of neuronal networks. In our group, we study synaptic transmission, synaptic plasticity and the development of this amazing modular structure.

Current research

Long-term synaptic plasticity is a ubiquitous neuronal mechanism that controls synaptic strength over hours and possibly days. It is likely to contribute to the establishment of memory formation in the adult brain. It has also been shown to underlie activity-dependent selective wiring in the immature developing brain.

In order to distinguish between these two forms of long-term synaptic plasticities, we study two distinct periods of life in the cerebellar cortex of mice 1) during the first week after birth and 2) in the “true adult” (i.e. after puberty). In these two scenarios, we look at the role of glutamate and GABA-ergic systems (release/receptors) as well as the role of cellular actors that contribute to the ensemble activity such as the connexin-like proteins named Pannexins.

Biomedical perspective

It is widely recognized that Autism and Schizophrenia are often associated with cerebellar defects and/or abnormalities. We are currently developing collaborations with psychiatrists to study this association that may allow us to better understand the nature, and perhaps the origin of these developmental diseases. In this context, we will study synaptic transmission and plasticity in both adults and developing animal models with early cerebellar lesion as well as in models of Autism and Schizophrenia.

As an example of ongoing work at the lab, we recently made the cover of The Journal of Neuroscience, November 10, 2010 with our description of the role of NMDA receptors of adult Purkinje cells in long-term depression.


Calcium imaging in a living cerebellar Purkinje cell loaded with the calcium-sensitive dye Oregon Green BAPTA-2 in a mouse cerebellar slice.: This picture shows in false colors the projection of the resting level of fluorescence acquired by a confocal laser microscope on multiple planes of the cell. Variations of calcium intensity can be detected in spines in response to climbing fiber stimulation. This calcium signaling is partly mediated by NMDA receptors in adult rodents and plays a key role in synaptic gain control.
