Neuro-Imaging Features Associated with Human Intelligence
✒️ Abstract:
Intelligence is a product of the brain, which includes several regions. Characteristics of the brain regions and their connectivity play key roles in the brain functions. Brain connectivity includes anatomical/structural connectivity and functional connectivity, which can be noninvasively evaluated using neuroimaging modalities such as Diffusion Tensor Magnetic Resonance Imaging (DTMRI) and functional Magnetic Resonance Imaging (fMRI), respectively. In addition, a variety of signal and image processing algorithms as well as detection, estimation, and pattern recognition methods need to be employed. In this presentation, I will introduce recent approaches and findings on the associations among the measures of the human intelligence and those of the neuroimaging data. To this end, I will first talk about the morphometry of the brain regions and their relations with the human intelligence. Next, I will elaborate on the applications of DTMRI and resting-state fMRI to the investigation of the human intelligence. Then, I will talk about the use of the multi-modal DTMRI-fMRI data to shed light on the intelligence. I will conclude with a summary of the recent achievements and the remaining challenges.

Time and state dependent fMRI functional connectivity: Analysis methods
✒️ Abstract:
In order to precisely evaluate the functional organization of the brain by fMRI, it is required to consider the couplings of brain regions variable by time or brain state. Some analysis methods for this characterization will be discussed in this talk including sliding window correlation, functional network connectivity through ICA, and network based measures. Few instance studies will be presented in which we used state dependent connectivity or differential connectivity graph to capture the variations in brain connectivity pattern among various brain states during a task.

Object-based spatial encoding in fronto-parietal reach network
✒️ Abstract:
Primates' hand is one of their significant features. Reaching towards objects to grasp or manipulate them is one way that primates use to interact with their surrounding physical environment. During reaching movement neurons of the fronto-parietal network of human and non-human primates brain encode spatial location of movement targets relative to the body. In my talk I will show when movements are directed towards behaviorally relevant objects, there is another level of spatial encoding by the same neurons which is relative to the object. I will show that spatial encoding is dynamic and changes at different stages of movement planning.

Social preference and Information Sharing
✒️ Abstract:
Human beings have stepped into an era of information. In this era, information sharing plays an important role in social communication. It has been shown that information sharing is rewarding for people. Besides, social preference is widely studied in many game theoretical experiments and has revealed the attitudes of people toward helping others, fairness, trust and reciprocity. The main point in many task is that people show social preference in spite of the cost they pay. All these facts predict that if we design a task, that in which information sharing does not cost for the beholder of information, people should share their information for any given gain. Examining the behavior of people in our information sharing task showed a variety of patterns that economically irrational. Moreover, the theory of dual process for decision making shows two dissociable systems, one fast and intuitive and other slow and reflective. The trends of reaction times of people during sharing and not sharing reveals the contribution of these two systems in the behavior of participants. In sum, there is an individual difference in the sharing tendency of people, which is consistent with their intrinsic attitude toward others. There are many people that don’t give their personally useless information to the others, even they can get the half of the gain of the other.

The Role of the Basal Ganglia and Superior Colliculus in Perceptual Decision-Making
✒️ Abstract:
Perceptual decisions arise after considering the available sensory evidence. When sensory information is unreliable, a good strategy is to rely on previous experience in similar situations to guide decisions. It is well known that people with Parkinson’s disease (PD) are impaired at value-based decision-making. How patients combine past experience and sensory information to make perceptual decisions is unknown. We developed a novel, perceptual decision-making task and manipulated the statistics of the sensory stimuli presented to patients with PD and healthy participants to determine the influence of past experience on decision-making. We show that patients with PD are impaired at combining previously learned information with current sensory information to guide decisions. We modeled the results using the drift-diffusion model (DDM) and found that the impairment corresponds to a failure in adjusting the amount of sensory evidence needed to make a decision. These results led us to explore how decision criteria are established and adjusted. To understand this, trained monkeys performed a novel, "Yes-No" detection decision task that isolated changes in decision criterion from changes in decision sensitivity. We computed neuronal measures of sensitivity and criterion from behavioral responses as well as from neuronal activity measured from the superior colliculus (SC). We found that SC neuronal activity correlated with the decision criterion regardless of the location of the choice report and that electrical manipulation of activity within the SC produced changes in decisions consistent with changes in decision criteria largely independent of the choice report location. Our correlational and causal results together provide strong evidence that SC activity signals the position of a decision criterion.
