Decreased synaptic and mitochondrial density in the postmortem anterior cingulate cortex in schizophrenia
2015, Schizophrenia ResearchCitation Excerpt :In the deep layers of prefrontal cortex of non-human primates, asymmetric axospinous synapses are formed mainly by cortical association inputs from the contralateral hemisphere, local collaterals of excitatory neurons (Bannister, 2005; Morecraft et al., 2012; Vogt and Pandya, 1987), and contacts from calretinin-labeled cortical interneurons (del Rio and DeFelipe, 1997; Melchitzky et al., 2005). Thalamic afferents other than the medial dorsal nucleus terminate in the deep layers of the cortex in rat (Shibata, 1993) and in monkey (DeFelipe and Jones, 1991) and may also innervate the ACC in human. Another source of excitatory inputs onto spines is from the amygdala (Cunningham et al., 2002) another pathological region in SZ (Benes, 2010).
Quantitative estimation of the primary auditory cortex in human brains
2004, Brain ResearchCitation Excerpt :Every 10th section was stained for the demonstration of the Nissl substance using the thionin stain after lipid removing with two successive steps in a solution of chloroform and ethanol at 50% each one. These thionin-stained sections allowed us to delimitate the cytoarchitectonic boundaries of the primary auditory areas; however, verification of these areas was performed in four hemispheres (30–93 and 7–96) using the parvalbumin immunohistochemical technique that stains the inhibitory subpopulation of gabaergic interneurons representative of the primary sensory cortex [10,15](Fig. 2). For this, sections used for parvalbumin immunostaining method were previously treated to eliminate endogenous peroxidase activity with a step of 10% hydrogen peroxide in phosphate-buffered saline (PBS) for 10 min, and nonspecific binding was blocked by a step in 1% normal horse serum for 2 h at room temperature.
Selective deficits in prefrontal cortical GABAergic neurons in schizophrenia defined by the presence of calcium-binding proteins
2002, Biological PsychiatryCitation Excerpt :Parvalbumin-positive cells appeared to be nonpyramidal and consisted of a variety of morphologies, including small ovoid perikarya, large multipolar neurons, and occasionally bitufted cells (Figure 1 d). A dense plexus of immunoreactive material was also distributed throughout the neuropil of layers III, IV, and V and consisted of stained processes and puncta, which have been shown to represent axonal terminals (DeFelipe and Jones 1991). Calbindin-immunoreactive neurons were present throughout the cortical width and were predominant in layer II and superficial layer III (Figure 1b).
