From the introduction: "There are two variants of fronto-temporal dementia: a behavioral variant (behavioral FTD, bvFTD, Neary et al. (1998)), which causes changes in behavior and personality but leaves syntax, phonology and semantics relatively intact, and a variant that causes impairments in the language processing system (Primary Progessive Aphasia, PPA (Gorno-Tempini et al., 2004). PPA can be subdivided into subtypes fluent (fluent but empty speech, comprehension of word meaning is affected / `semantic dementia') and non-fluent (agrammatism, hesitant or labored speech, word finding problems). Some identify logopenic aphasia as a FTD-variant: fluent aphasia with anomia but intact object recognition and underlying word meaning."

Improving estrus detection accuracy could improve sow conception rates,leading to higher production efficiency. Current observation-based estrusdetection practices are labor intensive and less accurate. Around estrus, bodytemperature and activity change. Therefore in this study a telemetric monitoringsystem for body temperature and activity was tested. Firstly Templant2 sensors(TeleMetronics) were validated under lab conditions for temperatures from 35°Cto 45°C, using a water basin with a Julabo heater and a P600 thermometer.Activity measurements were validated with the sensors attached to a stick,simulating sow movements. Secondly, sensors were attached externally to 4gilts and 4 sows for 30 minutes, testing functionality. Thirdly, activity of sowswas recorded manually for 3 days around estrus. Results showed that under labconditions temperature results of sensors, heater and thermometer were highlycorrelated (linear regression, R2=0,96; slope 1,1). Simulated activitiescorresponded consistently with peaks in sensor values. Activity was measuredreliably with the sensor attached externally to the sows. On the farm, sowsshowed more activity (manual observations, P<0.05 for standing up, lying down,sitting down and walking) the day before insemination. We conclude thatmonitoring activity and body temperature is a promising tool for estrousdetection in sows.

Previous event-related potentials (ERP) studies on the processing of emotional information in sentence/discourse context have yielded inconsistent findings. An important reason for the discrepancies is the different lexico-semantic properties of the emotional words. The present study controlled for the lexico-semantic meaning of emotional information by endowing the same person names with either positive or negative valence. ERPs were computed for positively and negatively valenced person names that were either congruent or incongruent to previous emotional contexts. We found that positive names elicited an N400 effect while negative names elicited a P600 effect in response to the incongruence. These results suggest that the integration of positive and negative information into emotional context exhibits different time courses, with a relatively delayed integration for negative information. Our study demonstrates that using person names constitutes a new and improved tool for investigating the integration of emotional information into context.
