Comprehending Events On The Fly: Inhibition And Selection During Sentence Processing, Yanina Prystauka

Master's Theses

In our everyday conversations we talk about how things or people change. Instantiations of objects in their different states need to be maintained during language comprehension for future selection of the relevant state, as in The chef will chop the onion. And then/but first, she will weigh the onion. Previous fMRI studies (Solomon et al, 2015) demonstrated that selecting between multiple competing representations of the same object token, such as the intact and the chopped onion, elicits increased activation in the brain area associated with conflict resolution -- left pVLPFC. When there is no cue to the earlier introduced …

Neurophysiological Characteristics Of Magnetic Seizure Therapy Vs. Electroconvulsive Therapy In Geriatric Patients With Severe Depression, Monica T. Ly

Master's Theses

Objective: Magnetic seizure therapy (MST) is under development as an alternative to electroconvulsive therapy (ECT), as it offers reduction in depression symptoms with fewer adverse cognitive effects. This study examined the feasibility and efficacy of MST versus ECT in a randomized trial of geriatric patients with severe depression, then compared the neurophysiological characteristics of seizures induced by MST or ECT and investigated potential links between seizure expression and therapeutic response.

Method: Six patients (mean age: 64.8) with severe depression were randomized to receive MST (n=3) or ECT (n=3) until maximal antidepressant effect (mean number of sessions: 14.67). Depression symptoms were …

Effects Of Active And Observational Experience On Eeg Activity During Early Childhood, Lauren Bryant

Master's Theses

How we encode and understand others’ actions is a core problem in social learning. In recent decades, the human neural mirroring system (NMS) has been implicated as a potential neural mechanism of action understanding. To investigate the effects of experience on NMS activity, we manipulated 3– to 6-year-old children’s (N = 16) active and observational experience with two tools and then examined EEG mu (7-10 Hz) and central beta rhythm (17-21 Hz) desynchronization as measures of NMS activity during observation and execution of these actions. Children exhibited neural mirroring within both individualized and standard mu bands. Although mu and …
