    Sammanfattning : The cholinergic C-bouton is a large nerve terminal type exclusively contacting motoneuron cell somata and proximal dendrites. C-boutons are characterized by subsurface cisterns found beneath the postsynaptic membrane, which is an exclusive feature for these nerve terminals. The origin of the C-boutons is unknown. LÄS MER

  2. 2. On age related changes in axons and glia of the central nervous system

    Nyckelord :Aging; synaptic input; spinal cord; hippocampus; amino acid neurotransmitters; astrocyte; microglia; oligodendroglia; C bouton; cholinergic; monoaminergic; cytokine;

    Sammanfattning : A growing body of evidence shows that phenotypic changes including axon aberrations, rather than loss of neurons, account for behavioral impairments during aging. The present thesis was undertaken to investigate the occurrence of axon aberrations in relation to transmitter identity, glial reaction and sensorimotor disturbances. LÄS MER
