Szabolcs Kéri

Schizophrenia as an example for "de-construction"
in consciousness research:

NEUROCOGNITIVE MECHANISMS OF SCHIZOPHRENIA:
FROM SENSORY GATING TO SELF-MONITORING

1. Definition and phenomenology of schizophrenia: psychotic, disorganized, and negative symptoms. Some aspects of etiology.

2. Basic cognitive disturbances and their neuronal substrates in schizophrenia

2.1. Prefrontal dysfunction: working memory, Wisconsin Card Sorting Test and the dopaminergic regulation of memory fields.

2.2. Semantic memory and temporal lobe pathology: fluency tests, fronto-temporal dysconnection, N400, categorization and thought disorder.

2.3. Sensory gating and early visual information processing: P50, continuos performance test (CPT) and backward masking. Phoneme categorical perception, mismatch-negativity (MMN), and P300.

3. The cognitive psychopathology of schizophrenia

3.1. Willed action, negative symptoms and the frontal lobes.

3.2. Self-monitoring: mechanisms of auditory hallucinations and delusions of reference and alien control. Dysconnection syndromes in schizophrenia.

3.3. Theory of mind: cingulate dysfunction, autism and paranoid delusions.

From elementary visual perception to recognition:
the binding problem
Some examples of parallel processing in the brain

A.The color-opponent and luminance channels (Schiller, Logothetis)

B.Color processing in both cortical and subcortical (mesencephalic) structures.

1. Progressive encephalization theories (example Tupaia belangeri)

C. Cognitive consequences:

1. The dorsal and ventral streams in the visual system

D. But if processing is modular, how does the information "get unified" into a single perceptual Gestalt?

1.The binding problem

2.Increase of coherent firing in both hemispheres (Knyazewa, Engel)

3.Misplaced intentionality fallacies and homuncularisations.

E. Recognition of objects when they are viewed from different positions/perspectives

1.View-invariant coding cells in temporal cortex (Booth and Rolls)

F. Philosophical considerations

1. Intentionality, Synthesis (Husserl)

2.The temporal structure of consciouscness (Pöppel, Varela)

C. Some corollaries of conscious behaviour

Balázs Gulyás

  1. General and tuned attention
  2. Volition
  3. Receptor architecture and personality
  4. Talent and genius
