6. Differences in glutamatergic transmission onto interneurons and pyramidal cells in the rat hippocampus
Sammanfattning : In the human brain there are about 100 billion excitatory glutamatergic neurons and 10 billion inhibitory GABAergic neurons. During development, these neurons are synaptically wired together into neural networks, functionally prepared to perform the full register of brain functions, and to learn from experiences. LÄS MER
7. Plasticity and variation of synaptic responses in hippocampus. Role of AMPA and NMDA receptors
Sammanfattning : It is generally believed that synaptic plasticity in the central nervous system may underlie learning and memory as well as neuronal development. The most wellstudied examples of such synaptic plasticity are long-term potentiation (LTP) andlong-term depression (LTD). LÄS MER
8. Insulin promotes GABA signalling modulation in both the mouse hippocampus and human CD4+ T cells
Sammanfattning : Gamma-aminobutyric acid (GABA) is the most common inhibitory neurotransmitter in the adult mammalian brain, where it mediates several biological functions. Rapid inhibition is predominantly mediated by the activation of GABA-A receptors that are ubiquitously expressed across the central nervous system in a cell-, circuit-, or region-specific manner.

9. Studies on neuronal signaling in the hippocampus related to development, pathogenesis and treatment of mood disorders
Sammanfattning : The hippocampus is a central organ in the brain which is interconnected with different cortical regions and plays an important role in memory and learning processes. The anatomical position of the hippocampus together with the special sensitivity of its neurons renders it vulnerable to brain injury. LÄS MER
10. Studies on stress in African green monkeys (Cercopithecus aethiops) : Stress associated cortisol and prolactin levels, lymphocyte modulation and pathological changes in adrenal cortex, stomach and hippocampus in the African green monkey (C. aethiops)
Sammanfattning : African green monkeys (AGMs) are highly susceptible to captivity-induced stress. An investigation of spontaneous deaths of laboratory confined AGMs at the Institute of Primate Research, Nairobi, Kenya over a period of 7.5 years documented mild to severe gastric mucosal erosions and ulcers in 83 of 260 (32%) necropsies.
