2003 Salve Symposium and Course (earlier events))

Brain, behaviour and evolution:
from wetware to software
organized by András Lőrincz, Toshiya Matsushima and Péter Kabai
   

Next year? We'll get back to AVIAN SYSTEMS
(similar to the program of 2002)

  

 

This year we reviewed approaches to study circuitries in the brain (anatomy, electrophysiology, microdialysis) and concepts of building computational models. As students came from both sides of these two disciplines, we did not get into technical details but rather gave a broad overview.

Speakers were

  • Johan Bolhuis
  • Mark Eyre
  • Peter Kabai
  • András Lőrincz
  • Toshiya Matsushima
  • Aniko Schrott
  • Gábor Szirtes
  • Gergely Zachar
  
   

 

  
.
Single unit level
.
Toshiya Matsushima:

Basic biology of a firing neuron
- Intrinsic properties (negative resistance and bistability, rebound firing and their role in neural computation)
- Synaptic actions (diverse modes of synaptic excitation and inhibition)
Gábor Szirtes:
Model of a firing neuron
- why does it fire
- how does it fire
- what is changed by firing
Toshiya Matsushima:
Practical neurophysiology of a firing neuron
- Facts of extra- and intra-cellular recordings
- Interpretations of electrophysiological data
.
Simpler networks
.
Mark Eyre:

Anatomical identification of neuronal connections
Gabor Szirtes:

Praise of simplicity: structural research on an I&F based NN
Gabor Szirtes:
Reconstruction networks
- Order of learning
- Priming and repetition suppression
Toshiya Matsushima:
Neural basis of memory-based anticipation in the avian striatum: neural code of temporal proximity of anticipated reward and its functional significance.
- What is the memory for? Why do animals recall?
- Can we really observe mental representations by electrophysiology?
- Do the representations contribute to survival and reproduction?
- Does "cognitive neuro-ecology" yield a realistic approach?
Gergely Zachar:
Beyond the synapse
- extrasynaptic transmission
- in-vivo microdialysis: what does it measure?
- neurotransmitters or neuromodulators?
András Lőrincz:
Prediction in neuronal networks
- Input-output schemes
- Pattern completion in space (recognition by components)
- Pattern completion in time (reasoning, prediction)
- Pattern completion in space and time
András Lőrincz:
Control of reconstruction networks
- dynamics
- control = inverse dynamics
- precise control
- imprecise control
- robust control
András Lőrincz:
View from inside -- view from outside: Controlled reconstruction networks
- history of the comparator hypothesis in neurobiology
- comparator, match/mismatch detection, novelty, saliency
- distributed characteristics
- similarities between reconstruction network and robust control
- mapping to the neocortex
Brain region level
.
Anikó Schrott:

Functional database for the avian brain

The data base is available here
Péter Kabai:

Evolution of brain and intelligence
.
Philosophical issues
Johan Bolhuis:
Gábor Szirtes:
Philosophical issues: The homunculus paradigm
- Infinite regression
- Turing test
- Chinese room

András Lőrincz:

The question of intelligence
- Harnad: Cognition is categorization
- Biederman: Recognition by components
- What loops? Room for intelligence
