Full textDeep brain stimulation (DBS) is an established surgical therapy for movement disorders. The mechanisms of action of DBS remain unclear, and selection of stimulation parameters is a clinical challenge and can result in sub-optimal outcomes. Closed-loop DBS systems would use a feedback control signal for automatic adjustment of DBS parameters and improved therapeutic effectiveness. We hypothesized that evoked compound action potentials (ECAPs), generated by activated neurons in the vicinity of the stimulating electrode, would reveal the type and spatial extent of neural activation, as well as provide signatures of clinical effectiveness. The objective of this dissertation was to record and characterize the ECAP during DBS to determine its suitability as a feedback signal in closed-loop systems. The ECAP was investigated using computer simulation and
First, we developed DBS-ECAP recording instrumentation to reduce the stimulus artifact and enable high fidelity measurements of the ECAP at short latency.
Second, we characterized ECAPs measured during thalamic DBS across stimulation parameters in anesthetized cats, and determined the neural origin of the ECAP using pharmacological interventions and a computer-based biophysical model of a thalamic network. This model simulated the ECAP response generated by a population of thalamic neurons, calculated ECAPs similar to experimental recordings, and indicated the relative contribution from different types of neural elements to the composite ECAP. Signal energy of the ECAP increased with DBS amplitude or pulse width, reflecting an increased extent of activation. Shorter latency, primary ECAP phases were generated by direct excitation of neural elements, whereas longer latency, secondary phases were generated by post-synaptic activation.
Third, intraoperative studies were conducted in human subjects with thalamic DBS for tremor, and the ECAP and tremor responses were measured across stimulation parameters. ECAP recording was technically challenging due to the presence of a wide range of stimulus artifact magnitudes across subjects, and an electrical circuit equivalent model and finite element method model both suggested that glial encapsulation around the DBS electrode increased the artifact size. Nevertheless, high fidelity ECAPs were recorded from acutely and chronically implanted DBS electrodes, and the energy of ECAP phases was correlated with changes in tremor.
Fourth, we used a computational model to understand how electrode design parameters influenced neural recording. Reducing the diameter or length of recording contacts increased the magnitude of single-unit responses, led to greater spatial sensitivity, and changed the relative contribution from local cells or passing axons. The effect of diameter or contact length varied across phases of population ECAPs, but ECAP signal energy increased with greater contact spacing, due to changes in the spatial sensitivity of the contacts. In addition, the signal increased with glial encapsulation in the peri-electrode space, decreased with local edema, and was unaffected by the physical presence of the highly conductive recording contacts.
It is feasible to record ECAP signals during DBS, and the correlation between ECAP characteristics and tremor suggests that this signal could be used in closed-loop DBS. This was demonstrated by implementation in simulation of a closed-loop system, in which a proportional-integral-derivative (PID) controller automatically adjusted DBS parameters to obtain a target ECAP energy value, and modified parameters in response to disturbances. The ECAP also provided insight into neural activation during DBS, with the dominant contribution to clinical ECAPs derived from excited cerebellothalamic fibers, suggesting that activation of these fibers is critical for DBS therapy.

Full textBackground: Sensitive emotional interaction with one’s parent during infancy is recognised as fundamental to healthy infant cognitive, social, emotional and physical development. Mothers with Borderline Personality Disorder (BPD) are known to have disturbed relationships with their infant(s), characterised by high levels of maternal stress, low parental self-efficacy, intrusiveness, hostility, avoidance, and in some cases, abuse. These relational difficulties may be related to problems perceiving their infant’s nonverbal emotional cues. Previous studies have found impaired facial emotion recognition in individuals with BPD using adult face stimuli; however, the exact nature of this abnormality is not yet established. No research has examined the ability of mothers with BPD to accurately identify their infant’s facial expressions of emotion. In light of the plethora of research highlighting the social and emotional disturbances associated with BPD, this research is important for furthering scientific understanding of the socio-emotional deficits underlying the disorder, and to identify targets for treatment and remediation in at-risk mother-infant dyads. Scope: This research extends existing knowledge by examining face emotion recognition ability in women with BPD using adult face stimuli of varying emotional intensities, and is the first to use novel infant face emotion stimuli to examine the relationship between infant emotion perception and key clinical and parenting variables associated with BPD. Purpose: The purpose of this research is to examine emotion recognition performance in women with BPD and the underlying mechanisms associated with emotion recognition disturbances observed previously in this group. Study 1 will focus on adult face perception and processing. The eye movements (visual scanpaths) of participants will be recorded while they view adult face emotion stimuli to examine visuo-cognitive performance. Affect recognition will be assessed concurrently. Study 2 will focus on infant face emotion recognition accuracy using the women’s own, as well as unknown, infant face images depicting three emotions (happy, sad and neutral) to examine relationships between infant face emotion recognition and key clinical and parental variables associated with BPD. Methodology: The total sample consisted of 14 women diagnosed with BPD and 16 control women. Women were recruited from parenting and mental health services within Hunter New England Area Health Service (HNEAHS). The women participated in Study 1 and 2 concurrently, and completed two assessment phases within each study. Of this sample, 14 women diagnosed with BPD and 16 control women participated in Study 1. In Phase One of this study, participants completed a clinical assessment and a set of self-report questionnaires. In Phase Two, approximately one month after completing Phase One, participants completed two visual scanpath tasks: the Adult Emotion Recognition Task (AERT) and the Adult Emotion Intensity Task (AEIT). In the AERT, stimuli consisted of male and female adult posers depicting one of five emotions (angry, sad, happy, fearful and neutral). In the AEIT, stimuli consisted of male and female adult images depicting happy, sad, neutral, angry or fearful expressions at varying intensity levels of 20%, 60%, 80%, and 100%. Affect recognition was assessed concurrently in both tasks using verbal report by participants. In Study 2, the sample consisted of 13 mothers diagnosed with BPD and 13 healthy control mothers who completed both the clinical and parenting questionnaires and the infant emotion recognition task (IERT) that comprised images of the mothers’ own, as well as unknown (control), infant faces depicting happy, neutral and sad expressions. Results: In Study 1, participants with BPD were found to be significantly less accurate in overall face emotion recognition ability than controls, but not so for visual scanpath performance where they performed similarly to controls, suggesting that emotion recognition deficits in BPD are not associated with an underlying facial information processing impairment. Some tentative support was also observed for a negative misattribution bias in the BPD group for neutral expressions, which were more often reported as being sad, followed equally by angry and fear. However, this trend dissipated after more rigorous follow-up analyses. In Study two examining infant face emotion recognition, mothers with BPD were found to display significantly poorer overall infant emotion recognition accuracy compared to control mothers. Recognition of neutral facial expressions provided greatest between-group discrimination, with mothers with BPD displaying significantly poorer accuracy for neutral infant expressions, negatively misattributing neutral for sad in the majority of cases. However, unexpectedly, the negative misattribution was not associated with key clinical and parenting variables in this cohort, although mothers’ age and duration of the BPD were related, suggesting that chronicity of illness, rather than severity of symptoms, impacted greatest on mothers’ perceptions of infants’ emotions. As expected, mothers with BPD did not show enhanced accuracy for recognising their own infant’s emotions compared with that of unknown infants. However, in contrast to expectations and previous literature, the healthy control mothers in this study also did not demonstrate enhanced accuracy when viewing their own infant’s emotions. General Conclusions and Implications: The findings from this research (both Study 1 and 2) show that while women with BPD have impaired emotion recognition ability, their visual processing of facial information appears intact. The research findings also highlight an important trend of negative misattribution of neutral affect in women with BPD, which may have significant impact on their parenting of infants, perhaps perceiving them to display more negative emotions than they actually do. Older mothers with greater BPD chronicity are particularly vulnerable and the findings highlight the need for both further research and early intervention in this sub-group of mothers with BPD. The development of specific remediative interventions that target infant face recognition deficits in mothers with chronic BPD with the aim of improving the outcomes for at risk mother-infant dyads are required.
