  2. 21. Neurochemical regulators of the septohippocampal pathway : role in spatial and aversive learning

    Author : Elin Elvander Tottie; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Acetylcholine; muscarinic receptor; galanin; serotonin; 5-HT1A receptor; glutamate; NMDA receptor; water maze; passive avoidance; septum; hippocampus; learning; memory; spatial; aversive; emotional; cognition;

    Abstract : The aim of this thesis was to investigate the significance of major neurotransmitters in the septohippocampal pathway for hippocampal-dependent learning and memory. The cholinergic and GABAergic neurons in the medial septal/vertical limb of the diagonal band of Broca area (MS/vDB) projecting to the hippocampus, constitute the septohippocampal pathway, which has been implicated in a number of important functions such as attention, anxietylike behavior and hippocampal-dependent learning and memory.

    Keywords : ;

    Abstract : As a social species, humans are not only driven by the pursuit of necessities such as food and shelter, but also complex processes such as social interactions. To navigate our everyday life, we use information gathered throughout a lifetime of social interactions in which we learn from others and their actions but also, and not less importantly, about others.

    Keywords : ;

    Abstract : Depression is a multifaceted disease which is marked by cognitive and emotional memory impairments. It is characterised by an imbalacement of serotonergic and glutamatergic system in brain areas such as hippocampus and prefontal cortex. READ MORE
