Abstract:

Animal behaviour is coordinated by biological rhythms over multiple timescales. In the temporal cortex, rhythmic oscillatory activity in the 5 to 12 Hz theta frequency range supports behaviour through temporal windows of changes in excitability and circuit computation. Subcortical inputs, including those from the medial septum are thought to generate the theta oscillatory activity. However, the rules of innervation of identified types of cortical cells in different cortical regions by a diverse population of septal neurons are largely unknown. During my DPhil studies, I tested the hypothesis t

Abstract:

Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene are known to cause late-onset, familial forms of Parkinson’s Disease, with prevalence up to 40% in specific populations. These mutations are also linked to sporadic PD, highlighting the importance of the related protein in the development of the disease. LRRK2 is a large, complex, multi-domain protein, with two main enzymatic activities: a GTPase domain (bearing three pathogenic mutations) and a kinase domain, in which the most common mutation (G2019S) is found. Even though the precise cellular functions of LRRK2 are not known, LRRK2

Abstract:

Alcoholism is a complex neurological disorder characterized by loss of control in limiting intake, compulsion to seek and imbibe ethanol, and chronic craving and relapse. It is suggested that the characteristic behaviors associated with the escalation of drug use are caused by long-term molecular adaptations precipitated by the drug’s continual administration. These lasting activity-dependent changes that underlie addiction-associated behavior are thought, in part, to depend on new protein synthesis and remodeling at the synapses. It is well established that mRNA can be transported to neuronal

By improving the stability of field recordings in in vitro electrophysiology, it was possible to investigate the molecular processes that determine the long-term changes in synaptic efficacy.

Abstract:

The synapse is essential for normal neuronal communication and synaptic abnormalities could underlie many neuronal pathologies leading to such diseases as epilepsy and autism. Recent reports suggest that the Wnt signaling pathway is essential for normal synaptic development and function. However the role of specific Wnt ligands and their downstream signaling molecules play in synapse formation and function remain unclear. PRICKLE1 (PK1) and PRICKLE2 (PK2) are downstream Wnt signaling molecules which are suggested to play essential roles in neuronal function. PK1 was recently shown to be mutate

Abstract:

Sensory deprivation in one modality can enhance the development of the remaining modalities via mechanisms of synaptic plasticity. Mice of C3H strain suffers from RD1 retinal degeneration that leads to visual impairment at weaning age. Independently on the retinal degeneration there is also present olivocerebellar degeneration caused by Lurcher mutation. This neurodegenerative disorder causes motor deficits, increased CNS excitability as well as changes in synaptic plasticity. The aim of this study was to evaluate a role of whiskers in compensation of the visual deficit and to assess the influ

Abstract:

PART I Animals need to constantly evaluate their external environment in order to survive. In some cases the internal state of the animal changes to cope with it’s surrounding. In our study we wanted to investigate the role of amines in modulating internal states of Drosophila. We have designed a behavioral paradigm where the flies are fixed in space but can walk on a small styrofoam ball suspended by a gentle stream of air. The walking activity of flies was used as behavioral readout. PART I Animals need to constantly evaluate their external environment in order to survive. In some cases the

Abstract:

Dissertação de Mestrado em Ciências da Saúde<br>Tau is a cytoskeletal protein which binds to microtubules and regulates their assembly and stabilization. Interestingly, recent evidence suggests novel roles of Tau in synaptic structure and function. On the other hand, Tau hyperphosphorylation and subsequent malfunction is suggested to be a key parameter of synaptic dysfunction and atrophy and memory loss that characterized Alzheimer´s disease. Indeed, cumulative evidence from experimental studies demonstrated that absence of Tau blocked Aβ detrimental properties on synaptic dysfunction and loss

Abstract:

碩士<br>國立臺灣大學<br>臨床醫學研究所<br>93<br>Advances in medical technology have significantly improved survival among medically compromised premature babies. However, poorly managed pain during this period will result in long-term physiologic and behavioral consequences. Animal studies reveal that neonatal peripheral inflammatory pain results in long-standing changes on the development of nociceptive neuronal circuitry. Morphologically, fine primary afferent fibers termination area in spinal cord dorsal horn expands longitudinally and sprouts into deeper lamina. Electrophysiologic study shows increase in
