Solvent-triggered shape change in gradient-based 4D printed bilayers: case study on semi-crystalline polymer networks.

We propose an approach to 4D print solvent-triggered, gradient-based bilayers made of semi-crystalline crosslinked polymer networks. Out-of-plane bending is obtained after immersion in the solvent, exploiting the different swelling degrees of the layers resulting from crosslinking gradients. Lastly, a beam model of the shape transformation is applied and experimentally validated.

An electrophysiological contribution to the study of language lateralization and prognosis of aphasia.

The study is aimed at identifying hemispheric language dominance in both the right-handed and left-handed participants. Eighteen right-handed and 18 left-handed young volunteers were invited to listen for 80 times to a 720 ms duration Italian word. Signals from 16 electrodes were averaged and displayed both as traces and maps.

The role of P300 in the recovery of post-stroke global aphasia.

Seventeen right-handed patients suffering from global aphasia caused by a recent stroke in the left-hemisphere were studied. Passive P300 auditory event related potential paradigm was applied every months for 6 months. Aachen subtests were used for evaluating comprehension.

Can we exploit event-related potentials for retraining language after stroke?

Purpose: To ascertain the utility of event-related potentials in studying language processing in patients suffering from aphasia.

Methods: Recent methods to evaluate event related potentials in response to spoken words were applied in two young patients suffering from a recent aphasia in whom expressive deficits were particularly marked. Recordings were made on three occasions for each patient at the same time of the day.

Event-related potentials to Italian spoken words.

Forty-four right-handed volunteers were invited to listen to Italian 5-letter words of different kinds, including non-words, digitally recorded. Signals from 16 electrodes were averaged and displayed both as traces and maps. When the same word was monotonously delivered to the subject, a positive component at 340 ms was recorded following the N100-P200 complex.
