Estimating brain age from structural MRI and MEG data: Insights from dimensionality reduction techniques
2021, NeuroImageCitation Excerpt :The brain structures that most reliably exhibited age-related changes included the putamen, thalamus, and caudate nucleus, which are important structures involved in relaying a variety of information across the brain, in sensorimotor coordination, and in higher cognitive functions (Grahn et al., 2008; Sefcsik et al., 2009; Sherman and Guillery, 2002). A number of stereological and MRI studies have reported atrophy in subcortical regions associated with aging, specifically in the putamen (Bugiani et al., 1978), amygdala (Coffey et al., 1992; Fjell et al., 2013), hippocampus (Fjell et al., 2013; Nobis et al., 2019), caudate nucleus (Krishnan et al., 1990), substantia nigra (McGeer et al., 1977), thalamus (Sullivan et al., 2004; Fjell et al., 2013), and cerebellum (Andersen et al., 2003; Good et al., 2001; Torvik et al., 1986). Recent studies using large subject cohorts have also reported an age-related decrease in the hippocampal and temporal lobe volumes (Nobis et al., 2019).

2018, Neurobiology of AgingCitation Excerpt :The development of noninvasive imaging techniques has fueled research into the aging brain in healthy individuals. Since magnetic resonance imaging (MRI) was first introduced in biomedical research in the 1980s, several pioneers performed small studies using this novel technique to assess macrostructural brain changes in aging (Gur et al., 1991; Jernigan et al., 1990, 1991; Krishnan et al., 1990; Pfefferbaum et al., 1994; Sullivan et al., 1995). After approximately one decade, large cross-sectional studies and population-based studies followed to inform about, for example, sex differences and brain changes in a large sample of healthy volunteers, instead of specific control subjects (Coffey et al., 1998; Good et al., 2001; Mu et al., 1999).

2013, Neurobiology of AgingCitation Excerpt :These findings support the contention that lower striatal Glu levels might represent fewer or less effective corticostriatal projections. This interpretation is also supported by evidence for age-related striatal volume loss that has not been shown as attributable to loss of medium spiny neurons (Brabec et al., 2003; de Jong et al., 2010; Krishnan et al., 1990; Raz et al., 2003b). If striatal volume loss with age is not because of loss of medium spiny neurons, it might instead reflect volume loss because of fewer cortical glutamatergic fibers in the striatum.
