"Is Cognitive Therapy Enduring or are Antidepressant Mediations Iatrogenic?"

 

Cognitive therapy appears to have an enduring effect that reduces risk for subsequent relapse and recurrence by about half relative to antidepressant medications following treatment termination. However, these conclusions are almost wholly derived from direct comparisons between prior cognitive therapy versus prior medication. Findings from the extended maintenance phase of our most recent trial suggest that cognitive therapy provided in combination with medication does little to prevent subsequent recurrence. These findings raise the concern that adding medications may interfere with the enduring effects of cognitive therapy as they do in panic. Moreover, depression appears to have “coarsened” over recent decades and there are concerns that antidepressant medications may suppress symptoms at the expense of prolonging the underlying episode. Antidepressant medications are known to work by perturbing the complex homeostatic regulatory systems that underlie affective response and differences in that perturbation are associated with risk for relapse following medication discontinuation. It remains unclear whether cognitive therapy truly has an enduring effect or antidepressant medications have an iatrogenic effect that that either interferes with cognitive therapy’s enduring effect or (even worse) prolong the length of the underlying episode. Studies are described that could resolve this issue and the potential implications discussed.

Approaches to Model-based Cognitive Neuroscience

Cognitive modeling has a rich history of formalizing and testing hypotheses about cognitive mechanisms within a mathematical and computational language, making exquisite predictions of how people perceive, learn, remember, and decide. Cognitive neuroscience aims to identify neural mechanisms associated with key aspects of cognition, using techniques like neurophysiology, electrophysiology, and structural and functional brain imaging. These two come together in a powerful approach called model-based cognitive neuroscience, which can both inform model development and model selection and help interpret neural measures. Cognitive models decompose complex behavior into representations and processes and these latent model states are used to explain the modulation of brain states under different experimental conditions. Reciprocally, neural measures provide data that help constrain cognitive models and adjudicate between competing cognitive models that make similar predictions of behavior. I will outline a first attempt to develop a taxonomy of different approaches to model-based cognitive neuroscience, often making references to our collaborative work at Vanderbilt, highlighting potential strengths and weaknesses of different approaches.

The evolution of parietal-frontal networks for specific actions in primates

For over ten years we have been using electrical stimulation of the cortex as the primary tool in our studies of posterior parietal-to-frontal motor cortex pathways that are mediating specific classes of motor behavior in primates. The electrical stimulation has been useful, as it gives us a lot of control over the behavior as we manipulate the networks. We have studied prosimian primates, New World monkeys, and Old World monkeys, as well as other mammals to reveal similarities and differences in the networks, and suggest how they might have evolved. Our anatomical and physiological studies have led to results that support a number of conclusions. Most important, all primates likely have interacting networks for eight or more classes of behavior that involve domains in posterior parietal cortex, premotor cortex, and primary motor cortex. The domains function as a feed-forward posterior parietal-to-premotor-to-motor cortex series. Electrically stimulating any domain evokes slight variations of a specific behavior as a result of focused feedforward projections. Domains interact in ways that modify or inhibit specific behaviors via lateral connections in each cortical region, and by feedback connections. Other inputs contribute to each cortical region to modulate the final behavioral outcome. Close relatives of primates, tree shrews and rodents, do not have the large posterior parietal cortex of primates, and their posterior parietal cortex plays a minor role in motor behavior. The extensive expansion of posterior parietal cortex that is found in humans suggests an increased and more varied role in sensorimotor behavior.

Fluctuations of fMRI activation patterns underlie the theta-band rhythmic effects of visual object priming

To efficiently interact with an ever-changing environment, the brain dynamically responds to sensory stimulation. Notably, whereas high-frequency gamma band activity may directly underlie neuronal spike coordination (Crick & Koch, 1990), slower waves carrying (multiplexing) faster waves appear to be a common perceptual coding strategy in the brain (VanRullen & Koch, 2003). Recent behavioral studies further suggest a theta-band rhythm (4-7 Hz) in the effects of attention and priming (e.g., Fiebelkorn, Saalmann, & Kastner, 2013; Song et al., 2014; Huang, Chen, & Luo, 2015). Here, I investigate three possible brain mechanisms that may lead to such rhythmic behavioral effects: 1) object representations may be rhythmic in the inferior temporal (IT) cortex; 2) Object representations may be constant, but attentional selection of the representations may be rhythmic; 3) Sensory sampling may be rhythmic as early as the primary visual cortex, therefore all the subsequent processes may also be rhythmic. To test these possibilities, activity corresponding to visual object priming was measured in regions of interest (ROIs) across the whole brain by using fMRI.  Critically, to examine rhythmic effects, time-resolved measurements of fMRI activation patterns were attained by varying trial-by-trial stimulus onset asynchrony (SOA) between prime and probe in small steps of 20ms (equivalent to a 50Hz sampling rate). Our behavioral results replicated previous findings, showing theta-band oscillations in the priming effects of reaction times as a function of SOA. More interestingly, multivariate pattern analysis of the fMRI data also demonstrated theta-band oscillations as a function of SOA and an out-of-phase relationship between congruent and incongruent conditions in the IT cortex. No such effects were found in the BA17 or the frontoparietal attention network. This study is the first to map theta-band rhythms across the whole human brain using fMRI. Our results suggest that object representation is oscillatory with theta-band rhythms in the IT cortex, providing insights to understanding the dynamic mechanisms underlying visual perception.
