investigate the neurobiology aspects of behavior. The first project studies the behavior under the influence of hormones, while the second one\u00a0studies behavior during drug addiction. For these studies, we use mice and rats as (pre-clinical) animal models.<\/p>\n<div>For hormones and behavior, we study the effect of anabolic androgenic steroids (AAS) in different behavioral components, including reproductive-related behaviors, anxiety, learning &amp; memory, and addiction. We are also interested in determining\u00a0the cellular and molecular mechanisms that occur in the brain after the presence of supraphysiological doses of AAS.<\/div>\n<div><\/div>\n<p>Our\u00a0second project studies the effect of deep brain stimulation (DBS) in morphine addiction. We have tested high and low-DBS frequencies aimed<span class=\"x_Apple-converted-space\">\u00a0<\/span>at the<span class=\"x_Apple-converted-space\">\u00a0<\/span>nucleus accumbens of the brain to determine the possible beneficial effects for the extinction of drug-associated behaviors. We would also like to note that this project has a molecular component, to determine the biological substrates underlying the effects of DBS. Results from\u00a0this study might\u00a0represent a potential adjunct for extinction-based therapies for treatment-refractory opioid addicts.<\/div><\/div>[vc_empty_space][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row equal_height=&#8221;yes&#8221; content_placement=&#8221;middle&#8221; bg_type=&#8221;image&#8221; parallax_style=&#8221;vcpb-default&#8221; bg_image_new=&#8221;id^508|url^https:\/\/md.rcm.upr.edu\/biomed\/wp-content\/uploads\/sites\/27\/2015\/02\/3.jpg|caption^null|alt^null|title^3|description^null&#8221; bg_image_repeat=&#8221;no-repeat&#8221; bg_override=&#8221;full&#8221; enable_overlay=&#8221;enable_overlay_value&#8221; overlay_color=&#8221;rgba(0,45,56,0.9)&#8221; css=&#8221;.vc_custom_1636475928645{padding-top: 140px !important;padding-bottom: 70px !important;}&#8221;][vc_column width=&#8221;2\/3&#8243; css=&#8221;.vc_custom_1575398300037{padding-top: 30px !important;padding-bottom: 30px !important;}&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243; css=&#8221;.vc_custom_1575398099490{padding-top: 30px !important;padding-bottom: 30px !important;}&#8221;][\/vc_column][\/vc_row][vc_row css=&#8221;.vc_custom_1575399260773{padding-top: 80px !important;padding-bottom: 25px !important;}&#8221;][vc_column css=&#8221;.vc_custom_1575399220241{padding-bottom: 60px !important;}&#8221;][vc_empty_space][\/vc_column][\/vc_row]<\/p>\n","protected":false},"featured_media":2148,"comment_status":"closed","ping_status":"closed","template":"","dt_team_category":[26],"class_list":["post-2147","dt_team","type-dt_team","status-publish","has-post-thumbnail","hentry","dt_team_category-personnel","dt_team_category-26","description-off"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/md.rcm.upr.edu\/biomed\/wp-json\/wp\/v2\/dt_team\/2147","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/md.rcm.upr.edu\/biomed\/wp-json\/wp\/v2\/dt_team"}],"about":[{"href":"https:\/\/md.rcm.upr.edu\/biomed\/wp-json\/wp\/v2\/types\/dt_team"}],"replies":[{"embeddable":true,"href":"https:\/\/md.rcm.upr.edu\/biomed\/wp-json\/wp\/v2\/comments?post=2147"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/md.rcm.upr.edu\/biomed\/wp-json\/wp\/v2\/media\/2148"}],"wp:attachment":[{"href":"https:\/\/md.rcm.upr.edu\/biomed\/wp-json\/wp\/v2\/media?parent=2147"}],"wp:term":[{"taxonomy":"dt_team_category","embeddable":true,"href":"https:\/\/md.rcm.upr.edu\/biomed\/wp-json\/wp\/v2\/dt_team_category?post=2147"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
