1. Feedback control of cerebellar learning
Sammanfattning : The ability to anticipate future events and to modify erroneous anticipatory actions is crucial for the survival of any organism. Both theoretical and empirical lines of evidence implicate the cerebellum in this ability. It is often suggested that the cerebellum acquires “expectations” or “internal models”. LÄS MER
2. A Purkinje cell Timing Mechanism. On the Physical Basis of a Temporal Duration Memory
Sammanfattning : The standard view of neural signaling is that a neuron can influence its target cell by exciting or inhibiting it. Learning is thought to involve strengthening or weakening synaptic connections. For most behaviors, the brain must learn to produce precisely timed activity patterns. LÄS MER
3. Gastric Inhibitory Polypeptide in the brain
Sammanfattning : The hippocampus is an area of active cell proliferation and neurogenesis within the adult mammalian brain. Adult neurogenesis is of great importance for the brain, since it increases neuroplasticity and the ability to respond to environmental stimuli. LÄS MER
4. An Associative Memory Trace in the Cerebellar Cortex
Sammanfattning : Classical conditioning of motor responses, e.g., the eyeblink response, depends on the cerebellum. In the theoretical works of David Marr (1969) and James Albus (1971), it was proposed that Purkinje cells in the cerebellar cortex learn to associate the neutral conditioned stimulus with the response.

5. Cerebellar Control of Classical Conditioning
Sammanfattning : It has previously been shown that the cerebellum is critical for classical conditioning. The experiments presented in this thesis aimed to study how the cerebellum controls conditioned eyeblink responses (CRs) and specifically the efferent path from the cerebellar cortex to the muscles.
