Attentional refreshing allows the maintenance of information in working memory and has received growing interest in recent years. However, it is still ill-defined and several proposals have been put forward to account for its functioning. Among them, some proposals suggest that refreshing relies on the retrieval of knowledge from semantic long-term memory. To examine such a proposal, the present...

Introduction: Anhedonia, a core symptom of Major Depressive Disorder (MDD), manifests as a lack or loss of motivation as reflected by decreased reward responsiveness, at both behavioral and neural (i.e., striatum) levels. Exposure to stressful life events is another important risk factor for MDD. However, the mechanisms linking reward-deficit and stress to MDD remain poorly understood. Here,...

Disruption of gamma–delta relationship related to working memory deficits in first-episode psychosis

Missonnier, Pascal ; Prévot, Anne ; Herrmann, François R. ; Ventura, Joseph ; Padée, Anna ; Merlo, Marco C. G.

In: Journal of Neural Transmission, 2020, vol. 127, no. 1, p. 103–115

Working memory (WM) deficits constitute a core symptom of schizophrenia. Inadequacy of WM maintenance in schizophrenia has been reported to reflect abnormalities in the excitation/inhibition (E/I) balance between pyramidal neurons and parvalbumin basket cells, which may explain alterations of the dynamics of gamma and delta oscillations. To address this issue, we assessed event-related gamma...

Just-in-time information retrieval and summarization for personal assistance

Bahrainian, Seyed Ali ; Crestani, Fabio (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019INFO014.

With the rapid development of means for producing user-generated data opportunities for collecting such data over a time-line and utilizing it for various human-aid applications are more than ever. Wearable and mobile data capture devices as well as many online data channels such as search engines are all examples of means of user data collection. Such user data could be utilized to model user...
