不同情绪面孔的视觉工作记忆表现差异 [The Performance Difference of Visual Working Memory between Various Emotional Faces]
2022
Among social-emotional stimuli, emotional faces occupy an important position, which specifically refer to human faces with certain facial expressions. The visual working memory is a limited workspace where information can be saved online and can be accessed and operated by advanced cognitive function during the maintenance period. A large number of behavioral and electrophysiological studies have shown that there are differences in visual working memory performance of different emotional faces. Specifically, angry faces can enhance the visual working memory performance; fearful faces may cause some damage to visual working memory; sad faces will impair face recognition encoding in visual wo…
Anatomical and electrophysiological study of the vomeronasal circuits: Amygdaloid response to odours and pheromones
2017
Rodents detect information concerning the world around them mainly through two chemosensory systems: the olfactory and the vomeronasal systems. In order to develop an appropriate behavioural response to their environment, these systems exhibit both functional and physiological convergence. Further understanding of the organization and function of the olfactory systems would allow us to comprehend how their information is integrated in the brain. In a first approach we performed a thorough analysis of the connections of key structures involved in the processing of vomeronasal information: the medial (Me) and the posteromedial cortical (PMCo) amygdaloid nucleus. Then, we enquire the populatio…
Lauksaimniecības marginalizācijas ietekme uz aizsargājamo zālāju saglabāšanos Latvijā
2018
Maģistra darba mērķis - noskaidrot, kāda ir lauksaimniecības marginalizācijas ietekme uz aizsargājamo zālāju saglabāšanos Latvijā. Pētījums aptver visu Latviju. Izmantoti dabisko zālāju izplatības dati uz 2015. gadu un dati par lauksaimniecības zemju apsaimniekošanu 2017.gadā, kā arī augšņu kvalitātes dati. Datu analīze veikta 5 x5 km tīkla šūnā, analīzei izmantojot aprakstošo statistiku (Manna-Vitnija U-tests) un veikta daudzfaktoru regresijas analīze ar Tweedie modeļa datu sadalījumu. 2015.gadā Latvijā aizsargājamie zālāji aizņēma 0,77 % (50 156 ha) no valsts teritorijas. Bieži sastopamie biotopi valstī aizņem lielāko platību - 41 169 ha, bet retie un kompleksie biotopi aizņem, attiecīgi,…
