Reduced dendritic branching (Baharnoori
et al., 2009; Fernandez de Cossio et al., 2017; Li et al., 2014; Zhang and van Praag, 2015) and dendritic spine
density have been observed in MIA (Coiro
et al., 2015). Altered innervation of dendritic
spines was observed in the cortex and the cerebellum (Coiro et al., 2015; Pendyala et al., 2017). Impaired
synaptic transmission, mainly in the form of reduced synaptic transmission
(Canetta et al.,
2016; Coiro et al.,
2015; Ito et al.,
2010; Oh-Nishi et
al., 2010; Patrich
et al., 2016a; Shin Yim et al., 2017; Zhang and van Praag, 2015) has been observed in the
cortex and hippocampus. In addition to the synaptic impairments, neurons in the
hippocampus have altered membrane properties that result in reduced excitability
(Patrich et al.,
2016b).
