Coding of stable and moving objects in the brain
Lobellová, Veronika ; Stuchlík, Aleš (advisor) ; Telenský, Petr (referee)
Spatial navigation in an environment is essential for one's survival. Animals need to monitor location of self and location of other animate or inanimate objects. Navigation is a hippocampus dependent process supported by activity of place cells. Object location in space is thought to be coded as a point of interest on cognitive map formed by place cells. Place cells change their firing fields, process known as remapping, when a new object is introduced into the environment. However we do not yet know how location of moving objects such as predators or other animals is presented on the cognitive map. This work summarizes findings of chosen studies concerning the role of hippocampus and place cells in spatial coding of stable and moving objects.

Mikrofluidika v řízení živých tvorů
Tesař, Václav
Microfluidics had recently interesting uses in biomedical sciences. Its development towards smaller scales has reached the stage making possible an interfacing with the brain cortex at the cellular level: reading and inputting the neural signals. The signals and their processing are mostly of electronic character, but fluidics plays in this application one of the key supporting roles. The contribution on the one hand lists therapeutical applications, but on the other hand notes current trend of military uses of insects or small rodents who can intrude into military establishments and gather there pictorial information.
