  1. 21. Estrogen effects on different neurotransmitters in rat hippocampus : implications for cognitive function

    Författare :Nahid Karrar El-Bakri; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The past decade has witnessed a growing interest in estrogens and their activity in the central nervous system, which extends beyond the reproductive functions. Estrogen is known to interact with different neurotransmitter systems. LÄS MER

  5. 24. Immunocytochemical studies of excitatory amino acid neurotransmitters and transporters in the spinal cord and nucleus submedius

    Författare :Stefan Persson; Neurofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; neurophysiology; neuropsychology; Neurology; VGLUT2; VGLUT1; pain; somatosensory; thalamus; immunogold; glutamate; aspartate; dorsal horn; excitatory amino acids; spinal cord; neurofysiologi; Neurologi;

    Sammanfattning : The amino acid glutamate is today regarded as the main fast excitatory neurotransmitter in the central nervous system and a large body of evidence support that glutamate serves as a neurotransmitter in primary afferent terminals in the spinal cord. Previous evidence also suggests that the closely related amino acid aspartate may serve a similar role in some primary afferent terminals. LÄS MER

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

    Författare :Susanna Kullberg; Karolinska Institutet; Karolinska Institutet; []
    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
