Neural modulations in the auditory cortex during internal and external attention tasks: A single-patient intracranial recording study
2022, CortexCitation Excerpt :The pioneering study of Hubel, Henson, Rupert, and Galambos conducted more than 60 years ago (Hubel et al., 1959) demonstrated that single units in a cat's auditory cortex enhanced their activity for more interesting stimuli [see also an even earlier work of Hernandez-Peon and colleagues (Hernandez-Peon et al., 1956), who observed attentional enhancement in a cat's cochlea]. Later, single-unit auditory cortex attentional modulation was found in macaque monkeys (Benson & Hienz, 1978; Hocherman et al., 1976). In humans − the focus of the present investigation − enchantment of activity of the auditory cortex by attention has been demonstrated using functional MRI (fMRI) (e.g., Paltoglou et al., 2011; Petkov et al., 2004; Pugh et al., 1996; Woodruff et al., 1996).

2016, NeuroImageCitation Excerpt :In the visual domain, this biases neuronal population activity as measured by fMRI such that specifically the attended property can be decoded from an ambiguous stimulus (Jehee et al., 2011; Kamitani and Tong, 2005, 2006; Niazi et al., 2014). Finally, neuronal firing rates of monkey single-unit recordings increase with selective spatial attention (Benson and Hienz, 1978). Selective attention to one particular stimulus feature in the visual domain is associated with pronounced modulation of the neuronal response by task-relevance (e.g. Davidesco et al., 2013; Harel et al., 2014).
Attention to natural auditory signals
2013, Hearing ResearchCitation Excerpt :Perhaps for these reasons, follow-up work on auditory processing in awake, behaving animals came only years later and focused primarily on simpler stimuli (such as clicks, tones, and white noise) driving neural responses in regions such as A1 that were better understood functionally and anatomically. These studies consistently reported an increase in the single-neuron response to a behaviorally-relevant stimulus during task engagement compared to passive or ignored conditions (Miller et al., 1972; Hocherman et al., 1976; Pfingst et al., 1977; Benson and Hienz, 1978; for a comprehensive review see Fritz et al., 2007a,b). Decades of research on learning-dependent plasticity in the auditory cortex has provided us with ample evidence that the response properties of auditory neurons are capable of changing to better respond to relevant stimuli (for reviews see Pienkowski and Eggermont, 2011; Jääskeläinen et al., 2007).
